Some experts think that giving growth hormone to children with constitutional growth delay may increase their growth rate without speeding up bone maturation. This treatment is experimental, and studies are planned to see if growth hormone will help these children.
Abnormal Growth
Although most children who are very short or tall are healthy and normal, there are children who have diseases or conditions that affect their growth. Remember that a child’s growth rate over time is a more important clue to the presence of a growth problem than his or her size. For this reason, regular, accurate measurements plotted on a growth chart are very important: A change in the children’s growth rate may provide the first hint of an underlying problem.
The known causes of growth failure and short stature fall into 3 major groups:

  • systemic diseases (diseases that have effects on the whole body).
  • endocrine diseases (deficiencies or excesses of hormones).
  • congenital conditions (present at birth).

Sometimes no cause can be found, this is called idiopathic short stature. Abnormal tall stature is most often caused by an endocrine disease or a genetic condition. The purpose of this section is to provide an overview of the causes of growth failure*
Systemic Diseases
Systemic diseases are those that have effects on the whole body. They impair growth by affecting the child s overall health and well-being. Any disease that is severe or poorly controlled can have a negative effect on a child’s growth
Nutritional problems are the most common cause of growth failure worldwide. Good nutrition is the cornerstone of normal growth. A balanced diet with the right number of calories and the right amount of protein is necessary to meet the needs of growing children. Several diseases of the digestive tract (gastrointestinal diseases) can cause food to be poorly absorbed, so that the body cannot use food properly. Failure to absorb nutrients and energy from food often leads to growth failure.
Some of the symptoms of nutritional or bowel disease include:

  • poor weight gain
  • abnormal weight for height
  • frequent nausea, vomiting, diarrhea or constipation
  • abnormal bowel movements
  • severe bloating or gas when milk or dairy products are eaten.

Treatment of digestive tract problems often involves a special diet. Children usually have normal growth after the problem is correctly diagnosed and treated.
Diseases of the kidneys, heart and lungs may lead to growth failure by causing the buildup of undesirable substances in the body and by interfering with the body s use of nutrients and energy. Children with diabetes, or “high sugar, sometimes grow poorly even when their blood sugar is fairly well controlled.
Severe stress can cause growth failure. Children who live in very unhappy or disturbed homes may stop growing for a while, then start growing again when their home life improves.
Endocrine Diseases
Endocrine diseases are those which involve deficiencies or excesses of hormones. A deficiency exists when there is not enough of a hormone in the body, excess means there is too much of a hormone in the body.

Hypothyroidism, or deficiency of thyroid hormone, can halt growth completely and can occur at any time. Growth failure may be the first sign of this disease in childhood. Other symptoms which may appear later include:

  • lack of energy and concentration
  • constipation
  • dry, rough skin and hair
  • hoarseness
  • feeling cold when others are warm
  • coarsening (“thickening”) of facial features.

Every child who is growing at a slower than normal rate should have the simple blood test to check for thyroid deficiency. This disease is treated easily by taking a thyroid pill every day. The child with growth arrest from hypothyroidism usually “catches up” and returns to his or her previous growth channel after treatment begins.
Cortisol (stress hormone) excess, or Cushing’s syndrome, is a less common cause of growth failure in children. In this disorder, weight often increases while height stays the same. Too much cortisol also causes thinning of the skin, easy bruising, softening of the bones, and muscle wasting and weakness. It may be caused by overactivity of the pituitary gland, a tumor in the adrenal glands (where cortisol is made) or overmedication with cortisol pills used to treat asthma and other diseases. A blood test is used to check the amount of cortisoi in the blood. If there is too much cortisol, additional tests are needed to find out what is causing the excess. The treatment depends on the cause. Early diagnosis of this problem is important because the longer it lasts, the less chance the child has of returning to a normal height channel.
Growth hormone (GH) deficiency may occur at any time during infancy or childhood. There are many causes of GH deficiency. Most of them involve damage to the pituitary gland before, during or after birth. The major sign of GH deficiency is a marked slowing of growth, usually to less than 2 inches (5 cm) a year. Children with GH deficiency have normal body proportions and normal intelligence, some may be overweight for height and have problems with low blood sugar. GH deficiency is diagnosed by doing special blood tests to look for GH in the blood. It is treated by giving the child injections of GH several times a week until the child reaches an adult height in the normal range or until the growing ends of the bones fuse.
Congenital Conditions
Congenital conditions are present at birth and result from a problem that occurs before the baby is born. A number of factors can affect the mother, the fetus or the placenta (the organ in the uterus that links mother and fetus) to cause intrauterine growth retardation, or slow growth within the uterus.
Babies who are born prematurely (early) but who are of normal size for their age usually will “catch up” and fall within the normal range for height and weight by 2 to 3 years of age, assuming that they are in good health. Some full-term babies are smaller than expected at birth. If a full-term baby weighs over 4 1/2 pounds and does not have any other problems, there is a good chance that he or she will “catch up” and be normal size by 2 to 3 years of age. Full-term babies who are very small at birth (under 4 pounds) are likely to remain small throughout life. No treatment is known to be consistently effective in increasing their height.
Many genetic syndromes (groups of signs and symptoms of a known abnormality) are associated with short stature and growth problems. One of the most common is Turner syndrome, which occurs only in girls. Girls with Turner syndrome have a missing or misshapen sex chromosome (“package” of genes) in many of their cells. The cause of this defect is not known. These girls have underdeveloped ovaries (female sex glands where eggs and female hormones normally are produced), they are under 5 feet in height as adults, and their intelligence is normal. Turner syndrome is diagnosed by doing a special blood test (karyotype) to look for damaged or missing sex chromosomes. Growth failure may be the only sign of this condition. Female hormones (estrogens) must be given to bring about full sexual development at the time of puberty because the girl s underdeveloped ovaries will not produce these hormones. Research is being done to see if growth hormone may increase the adult height of these girls.
There are more than 50 bone diseases that can affect height and growth. Children with one of these skeletal dysplasias, or chondrodystrophles, are very short and have abnormal body proportions, intelligence is normal. One of the most common genetic bone disorders is achondroplasia, a disease in which a child s arms and legs are short in proportion to body length, the head is often large and the trunk is normal size. Skeletal dysplasias involve abnormal formation and growth of cartilage and bone. No treatment is effective in increasing adult height
Idiopathic Short Stature
Children with idiopathic short stature do not fall into any of the normal or abnormal categories described above. As far as anyone can tell, they are normal physically and mentally and extensive lab test results are normal. Yet they will fall below the normal range for height as adults, and below what would be expected, given their parents heights. No treatment to increase adult height is known at this time. The effect of GH treatment on these children has not been studied yet.
True idiopathic short stature is much less common than subtle forms of the conditions described earlier. A careful review of the child s history and physical exam often reveals clues that are easily overlooked. Often there is overlap between conditions. A common example of this is the short child who has elements of both familial short stature and constitutional growth delay.
Not all causes of short stature and growth failure can be treated, but parents and doctors should be alert for changes that may signal the onset of a treatable growth problem. Even it the parents are reassured that their short child is healthy and normal, emotional problems related to size may exist. It is just as important to recognize and treat these problems as it is to recognize and treat the child s physical problems.
Psychological And Emotional Aspects Of Short Stature
Since children who are short often face teasing and other forms of emotional stress, they may have problems coping and adjusting. The following story highlights some of the problems any short child may face, regardless of the diagnosis.

Josh is a 12-year-old boy with constitutional growth delay. Although he has grown at a normal rate throughout childhood, he is below the 5th percentile line on the growth chart. His bone age is delayed by 2 to 3 years, so he is likely to reach a normal adult height. He has always been the smallest child in his class, and the size difference is getting more noticeable as some of his classmates begin their growth spurts:
Josh looks more like a 4th grader than a 7th grader. He is having school problems this year, after moving into a new junior high school. His teachers report that “he’s either a clown or a bully in class, and he just doesn’t pay attention.” He likes sports and is good at soccer, but the coach doesn’t want to let him try out for the team-he is afraid Josh will get hurt. The older boys at school sometimes pick him up and carry him around and call him “Peewee” and “Squirt.” He has started spending a lot of time alone in his room and doesn’t seem interested in anything. After his last visit to the pediatrician, he said, I’m sick of hearing how tall I will be in 10 years. I’m a shrimp now, and that’s all that matters.”
Although many short children adapt well to their size and may never have psychological problems because of being short, Josh’s story is not unusual. Our society places positive emphasis on height. Children (or adults) who are short may be the victims of teasing, name-calling, cruelty and prejudice. Different aged children will have different concerns and problems depending on their level of development and maturity. For instance, a preschooler may worry that it is his fault that he is not growing. Regression (acting like a younger child) may be seen in school-aged children, while teenagers are likely to be concerned about dating, driving and discrimination in school, sports and the job market.
Any child may deal with these frustrations by becoming depressed (withdrawn and unhappy) or by “acting out” (behaving in an angry, aggressive hurtful way). Whatever the behavior, it is important for parents to try to understand the feelings behind their child’s actions. If you feel things are getting out of control or are more than you can handle, talk to your pediatrician, he or she can give you some suggestions or direct you to someone who can help.
The Short School-Aged Child
Josh is experiencing some of the common and predictable problems faced by school-aged children who are short. Family, teachers and other children have a difficult time treating a short child according to age rather than size. Sometimes discussing this tendency with teachers and friends (young and old) may be helpful in overcoming it. Although Josh looks like a 9-year-old, he is 12. Being treated as it he were 9 makes it easy for Josh to act younger than he really is-and perhaps he feels safer and more secure in a dependent, immature role. Acting younger does not make him happier, but it is safer because less is expected of him. Facing challenges is an important part of growing up and, like any child, the short child needs to have chances to succeed as well as to fail.
There is a natural tendency for parents to shelter their short child from the outside world, but children need not be shielded completely from reality. A healthy approach is to provide love, encouragement, support and skills that will help the child deal with the “big” world and develop self-confidence and a sense of responsibility. Focus on your child’s strengths. Look for things the child does well and give him the chance to do his best. Be excited about his achievements, whatever they are.
One of the reasons Josh is having school problems this year is that he has just transferred to a different school and has to face new teachers and new classmates who are not sure how to act around him. If a child is in the same school for several years, he often will develop a special role in the class and the other children will get to know him and stop thinking of him as different. In other words, he becomes accepted. A change (moving, transferring to another school) is like starting all over again with teasing and name-calling. Some children, subjected to this kind of treatment, just give up, withdraw and do not make new friends. Sometimes an older or bigger child serves as “protector” or “bodyguard” for the small child. This may be helpful for the short child, as long as he does not depend on his “bodyguard” to fight all his battles.
The Short Child and Sports
Another issue facing Josh and his family involves sports. Sports are an important part of life for many children, and there is no reason why short children cannot participate and excel in athletic activities. Many sports require intelligence, strength and endurance more than tall stature. Soccer, tennis, karate, judo, gymnastics, wrestling, skiing, skating, squash, handball, racquetball, horseback riding, horse racing, bowling, golf, track, swimming-there is a long list of activities that give short children (and adults) a chance to compete successfully. A short child, like any other child, should be encouraged to find a sport he or she enjoys, work hard at it and do his or her best.
Making Life Easier for the Short Child
The most important step in making life easier for a short child is also the hardest, and that is recognizing and accepting the child’s size. Children need to feel loved and valued just as they are, whether short or tall, skinny or fat. Parents who constantly focus on a child’s height (or lack of it) may make the child feel that it is not okay to be the way he or she is. Once parents come to terms with their child’s size, they can talk about it with the child in an open and realistic way.
Children may have a hard time putting their feelings into words, but that does not mean they do not have feelings about being small. Short children know they are short by the time they reach school age, if not before. The short child may be relieved to have parents who can help him to identify and express his feelings about being different.
In addition to conveying a basic feeling of acceptance, there are some very practical ways a parent can help to make life easier for a short child. The following ideas, based in part on a section in Kate Phifer’s book, Growing Up Small, may be helpful:

  • Make the physical environment at home as comfortable as possible for the child. Walk through his or her daily routine and see how things look from a lower eye level. This is something parents and their child can do together. It is hard, for example, to hang up your coat if your can’t reach the hanger. Lowering rods and hooks in closets solves this problem. Children may do a better job of combing their hair it there is a mirror placed so they can see more than the top of their head. Steady footstools or stepladders throughout the house can make a big difference in how easily a child can take care of himself. Whatever changes you make around the house, make them as simply and quickly as you can. Don’t make a “big deal” out of what your are doing, or make the child feel that he or she is causing trouble by being small.
  • Teach your child ways of coping with the physical environment away from home. This may include practice in “speaking up” when he or she is stuck behind a high counter or needs help reaching a doorknob. Help your child to think about situations in public that cause awkwardness or embarrassment, and then help the child to come up with ideas for handling those situations. Help your child rehearse a response (“role-play”) until he or she feels ready to try it out in the real world to see how it works. It may take a few tries, but it should be worth the effort.
  • Help your child learn some of the social skills that may be taken for granted. Take your child with you when you go out, and teach him or her how to order food in a restaurant, pay the cashier at the store, ask for the right size in the shoe department. Have your child’s friends over often and help your child make them feel welcome. Encourage your child to join in group activities if he or she would like to. It may be hard at first, but it often gets easier as the children get to know each other.
  • Discuss your child’s size with teachers and friends (young and old). Explain how important it is that your child be treated according to age, not size. It is hard to resist the urge to carry around a cute and cuddly 5-year-old who looks 3, but it is important to treat the child like any other 5-year-old. This is true at home as well.
  • Helping with chores and jobs around the house is part of growing up for many children. It helps the child develop a sense of responsibility and gain a feeling of pride and satisfaction. Short children do not need to be excused from sharing in household chores. With a little creativity, a short child should be able to do almost anything around the house, the yard. or the school, comfortably and safely.
  • Dress your child according to age, not size, even if it sometimes means having clothes altered. A 6-year-old who is dressed in toddler clothes, complete with snap seams on the legs, most likely is going to be treated like a toddler. Going along with fads is part of being a teenager. Learning to sew may be one answer for the teen that can not find the right style in the right size.
  • Encourage your child to learn skills that allow for competition, no matter what his or her size. Music, drama, or dancing lessons, 4H clubs, sports-there are many activities that give children a chance to develop special skills and learn to work and play with others. Local schools and recreation departments are good sources of information about activities for children.

This is how long sex is supposed to last

Measuring the average time is not a straightforward matter. Universal Pictures

  • Discovering the “normal” amount of time sex is supposed to last is difficult because it’s not something people tend to monitor, and those who take notice might oversell their time.
  • A study timed 500 couples to determine what was normal, but they found that the average time ranged from 33 seconds to 44 minutes.
  • The median time sex lasted for the couples studied came out to 5.4 minutes.

If you’re a non-scientist, you might have once asked yourself, propped against the bedhead after disappointingly quick intercourse, how long does sex “normally” last?

A scientist, though, would phrase the same question in an almost comically obscure way: What is the mean intravaginal ejaculation latency time?

I know there’s a lot more to sex than putting the penis into the vagina and ejaculating, but the rest is not always easy to define. (Kissing? Rubbing? Grinding?) To keep things simple and specific, we’ll just focus on the time to ejaculation.

Measuring an average time to ejaculation is not a straightforward matter. What about just asking people how long they take, you say? Well, there are two main problems with this. One is that people are likely to be biased upwards in their time estimates, because it’s socially desirable to say you go long into the night.

The other problem is that people don’t necessarily know how long they go for. Sex isn’t something people normally do while monitoring the bedside clock, and unassisted time estimation may be difficult during a transportative session of lovemaking.

What does the research say?

The best study we have estimating the average time to ejaculation in the general population involved 500 couples from around the world timing themselves having sex over a four-week period — using a stopwatch.

That is as practically awkward as it sounds: Participants pressed “start” at penile penetration and “stop” at ejaculation. You may note this could affect the mood somewhat, and might perhaps not exactly reflect the natural flow of things. But — science is rarely perfect, and this is the best we’ve got.

So what did the researchers find? The most striking result is that there was a huge amount of variation. The average time for each couple (that is, averaged across all the times they had sex) ranged from 33 seconds to 44 minutes. That’s an 80-fold difference.

So it’s clear there’s no one “normal” amount of time to have sex. The average (median, technically) across all couples, though, was 5.4 minutes. This means that if you line up the 500 couples from shortest sex to longest sex, the middle couple goes for an average of 5.4 minutes each time they do it.

There were some interesting secondary results, too. For example, condom use didn’t seem to affect the time, and neither did men’s being circumcised or not, which challenges some conventional wisdom regarding penile sensitivity and its relationship to staying power in the sack.

It didn’t much matter which country the couples came from either — unless they came from Turkey, in which case their sex tended to be significantly shorter (3.7 minutes) than couples from other countries (Netherlands, Spain, the United Kingdom, and the United States). Another surprising finding was that the older the couple, the shorter the sex, contrary to the prevailing wisdom (probably peddled by older men).

Why do we have sex for so long?

As an evolutionary researcher, all this talk of how long sex lasts make me wonder: Why does it last any time at all? All sex really needs to achieve, it seems, is to put sperm into the vagina. Why all the thrusting and bumping? Instead of sliding the penis in and out many hundreds of times per sexual session, why not just put it in once, ejaculate, and then go have a lemonade and get on with the rest of the day?

Before you say, Because it’s fun to go in and out!, remember evolution doesn’t care about fun per se — it generally only “designs” things to be enjoyable if they helped our ancestors pass on their genes to future generations. For example, even though we like eating food, we don’t chew each mouthful of it for five minutes just to make the enjoyment last longer. That would be inefficient, and so we’ve evolved to find it gross.

Why we last so long is a pretty complicated question with no clear answer, but a clue may be in the way the penis is shaped. In 2003, researchers showed – using artificial vaginas, artificial penises, and artificial sperm (corn syrup) – that the ridge around the head of the penis actually scoops out pre-existing syrup from the vagina.

What this suggests is that men’s repeated thrusting might function to displace other men’s semen before ejaculating, ensuring their own swimmers have a better chance of reaching the egg first. Incidentally, this could explain why it becomes painful for a man to continue thrusting after ejaculating since that would risk scooping out his own semen as well.

So what to do with this information? My advice would be to try not to think about it in the throes of passion.

Despite the ‘in-out’ being fun, does it serve a purpose biologically? from www..com

You came here looking for an answer, and an answer I will give you: Sex should last one hour, 34 minutes, and 22 seconds—the exact runtime of Wayne’s World.

Shyeah, right! While I have a lot of respect (and follow-up questions) for anyone who’s regularly managing to bone for the duration of a feature film, of course I’m joking. There isn’t a specific length of time that sex should last, but people tend to conflate longer sex with better sex. Marathon sex sessions are used as a measurement of just how steamy an evening was. And while quickies can be fun, they should constitute a piece of a balanced sex life—not the whole thing. They’re like the candy and ice cream part of the food pyramid—very tasty, just not intended for everyday sustenance.

While there’s no magic number, one study back in 2005 in the Journal of Sexual Medicine asked a bunch of sex therapists for their opinions on how long sex should last. Their guidelines separated sex into four categories: adequate, too short, too long, and desirable. They rated penetrative vaginal sex that lasted from 1-2 minutes as “too short,” and sex that lasted 10-30 minutes as “too long.” Meanwhile, “adequate” sex lasted 3-7 minutes and desirable sex lasted 7-13 minutes.

It’s difficult to get good data on the amount of time the average person spends getting freaky—are you keeping track of how long you’re humping and pumping?—especially because sex can be defined in a myriad of ways. For example, some people (and most studies) are only counting penetrative sex, which isn’t a particularly effective way to measure sex, since it’s both extremely heteronormative and not the way most people with vaginas are orgasming.

So I asked a handful of women and nonbinary people how long they’d ideally like sex to last, and with a few exceptions, the answers settled around five to ten minutes of intercourse, and longer for foreplay.

One woman said her ideal was 10-15 minutes of foreplay and 10 minutes of intercourse: “I find I get rather impatient in bed, or perhaps I just haven’t met someone worth taking more time.” Another said, “I feel like this sounds short, but honestly 5-10 mins plus like 15-ish minutes of foreplay.” Another woman said, “I generally like sex to last 15-20 minutes, with intercourse being like maybe a quarter of that.” Two women and one nonbinary woman answered that their ideal sex session including foreplay would last an hour or so—which seems like an endeavor! Good for them!

It turns out people consistently say that they want sex to last longer than it does. Almost everyone I informally interviewed felt that their answers were shorter than average, when in reality almost all of them were either in line with or above the average duration of sex, which is around 5.4 minutes.

So while we’re all self-conscious that we’re shortchanging our down-and-dirty time, sex really doesn’t take that long—even for people who are completely happy with their sex lives. I don’t mean to suggest that shorter sex is better, by any means. But according to a Twitter poll asking, “Do you ever get bored during penetrative sex or want it to just be over already?” Eighty-two percent of the 819 participants said yes. The reason I knew to ask that (possibly leading) question is that I, too, have been bored during penetrative sex, just up there thinking about the fact that I need to check on the status of my car registration or how Joan Cusack hasn’t had a single leading film role (which is a damn shame).

According to another Twitter poll I conducted of 2,380 people who are on the receiving end of penetrative sex, most (61 percent) wanted the actual penetration to last about 5-10 minutes (without counting foreplay). Twenty-six percent said they wanted it to last longer than 11 minutes. For the most part, those who are penetrated don’t think that longer penetration is better, so you can stop thinking about your grandma playing baseball, or whatever it is you’ve been doing to try to avoid coming too soon.

So according to the data, rather than attempting a marathon jackhammer sesh, you should switch things up! In that study, the more sex acts that a couple did, the more likely both of them were to orgasm, and the benefit of multiple sexual acts was even more significant for women than for men. The lesson here is you don’t need to be having sex longer; you need to be having sex better.

How Well Does Travis Scott Know Kylie Jenner?

Here’s how many people the average person under 30 says they’ve slept with — and why they could be lying

  • Nectar Sleep surveyed Americans to discover how many sexual partners they had before settling down.
  • The average number for people who identify as men was 26, the average number for people who identify as women was 19.
  • But other studies have shown that people often lie about their number.
  • Comparing yourself to others is all too easy, especially when it comes to sex.
  • While sharing your number may be uncomfortable, it’s easy to wonder about other people’s.

There’s an episode of “Friends” in which Monica’s boyfriend Richard asks her how many people she’s slept with. After telling her his number is two, she’s embarrassed to share her higher number, clearly fearing judgment. This exchange leads Ross and Rachel to have a similar, equally awkward conversation, comparing their past.

While stigmas around sex are slowly dissolving, for many, these conversations can still feel incredibly uncomfortable and will be avoided at all costs. At the end of the day, however, it’s natural to be curious about how many people others have slept with.

Nectar Sleep has released a study perfect for anyone wondering what their fellow Americans numbers are. Broken down by the gender binary, the survey asked participants who identify as men and women aged 30 and below how many sexual partners they had before “settling down.” It wasn’t clear the respondents’ sexuality, or what they defined as “sex,” and the only people surveyed appeared to be on the gender binary.

For those who identify as men, the average number of sexual partners was 26. The average number of sexual partners for those who identify as women was a bit lower, coming in at 19.

It’s worth noting that these numbers are much higher than many previous studies, including one Superdrug, previously reported on by INSIDER, that put women at an average of seven and men at an average of six.

Data is usually hard to pin down because people also admit they aren’t truthful about their “number.”

Studies have shown that men often increase their “number” while women decrease theirs when asked, which can say a lot about our attitudes towards sex and gender. Also, “sexual partners” and “sex” can often mean different things to different people, especially depending on their sexuality.

So although we can only go off of what people respond to in surveys like this, it’s definitely worth noting that these numbers can often be inflated based on who you ask.

No matter what, you shouldn’t stress about your number

After reading all that data did you immediately compare it to your number? I know I did. While it’s all too easy to compare yourself to others in every aspect of life, it’s incredibly important to note that there is no “normal” when it comes to the amount of sexual partners you “should” have and sharing your “number” is up to you.

“If it’s relevant to understanding what you both do and don’t like sexually then that’s important for physically communicating between the sheets, but if it’s about tallying up who is more ‘sexually experienced’ then this will achieve nothing for your relationship,” dating expert Sarah Ryan told HuffPost UK.

All that matters is that you are having safe and consensual sex that makes you happy.

How number of sex partners differ by height, body mass

The expectation that tall men, for example, would have the most sex partners was only partially supported. In fact, there was little difference in number of sex partners across the height continuum, with one exception–only very short men reported notably fewer median sex partners (5) than men of other heights (7). In terms of average number of partners, men who were average to extremely tall reported one to three more partners than men who were shorter than average.

“These findings confirm that height is relevant on the mating market,” said David Frederick, Ph.D., assistant professor in psychology at Chapman University, and lead author on the study. “However, the relatively limited variation in sex partner number for men across much of the height continuum is difficult to explain. Research has repeatedly shown than women prefer men who are relatively taller than they are. It is possible that for most women there is a certain minimal threshold of height, after which they will consider a male as a potential sex partner, and thus men above that height will end up with similar numbers of sex partners.”

With regard to men and body mass index (BMI), the study revealed that men in the middle BMI ranges had the most extensive sexual histories. According to Dr. Frederick, “Normal weight men and overweight men reported the most sex partners, and underweight men reported the least. Although it may be initially surprising that more overweight men reported the highest number of partners, it is important to note that the medical classification of overweight does not necessarily map onto social perceptions of overweight. For example, George W. Bush was medically classified as overweight during his presidency, but few people would perceive him as overweight. Men who appear somewhat larger, more powerful, or more athletic generally report more sexual experiences than other men.”

With regard to women, underweight women had notably fewer partners than other women.

“There are numerous possibilities as to why underweight women had few partners,” explained Dr. Frederick. ” They may be highly dissatisfied with their weight and suffering from anorexia and thus not motivated to show their bodies; additionally, being underweight is associated with a relatively high mortality rate and/or they could be suffering from a variety of ailments that cause weight loss and thus have fewer sex partners because they are dealing with serious health issues.”

The relationship between their height and number of sex partners revealed no revelations other than very short women reported fewer sex partners compared with tall women.

A total of 60,058 participants with a mean age of 37 completed the survey. Of those, 52 percent were men and 48 percent were women. The study examined height, education, age, and body mass index (BMI) as predictors of sexual history among heterosexual men and women. The research explored to what extent height and body mass are traits that may be useful social cues about health, social status and heritable fitness.

The Luv Doc: Sex and the White American Male

Dear Luv Doc,

I never thought I would ever in my life write to you, yet here I am. Honest to God, I don’t want to fall into stereotypes, but here is the thing: I am a well-educated, mature, Hispanic woman who went through a formal, committed relationship with a white American man. After six years of being kind, patient, and totally comprehensive of my man to react and feel motivated to have sex with me, I could count with my two hands the number of occasions we had sex. I would like to move on and meet another white American guy. When I shared this with my girlfriends, they are all preventing me to do so; they claim there is nobody like a Latino to make love – even American girlfriends say so because they have had sad, similar situations like mine with white men arguing they don’t need that much. But there is something about the American culture that I really love. So, my question is obvious: Is it true American men don’t really need that much sex? And I don’t mean every day, at any time, but at least once a week.

– She Wants a White American

Well, you’ve certainly come to the right source. Who better to mansplain about white men than a white man? As a white male, I would like to patronizingly point out that there are plenty of non-white American men. In fact, it could be safely said that a majority of the world’s Latino men are American – thanks mainly to greedy, genocidal white men looking to make a buck. Here we are several centuries later and we’re still shitting the bed. Look at who we elected as president. Yeesh. White guys ruin everything. Why wouldn’t they ruin sex?

I have to admit, however, that after reading your missive, I did feel a bit defensive. Having been in a six-year relationship with a white man, you are probably well familiar with defensiveness as a response to criticism. My first knee-jerk response was, “Hey! White guys need sex more than twice a year … on average.” (Psst: This is where I patronizingly point out that I did the math on your word problem and divided six by 10 and then rounded up. White guys love math.) Then I thought, “Wait … do white guys really need sex? Or do they just want it?” Then I sort of went down this Catholic priest wormhole and … well … let’s just say that when it comes to sex, there seems to be a strong correlation between want and need.

Then I went into research mode – and by that, I mean I went to the 2018 Pornhub Year in Review – and my suspicions were confirmed. White American guys do like sex more than two times a year! In fact, guess who watched more porn videos than any other nationality? U-S-A! U-S-A! That’s right, in 2018, Americans watched more porn on Pornhub than any other country on Earth … followed, of course, by our white would-be colonizer, the UK. Here’s the good news: 72% of those porn watchers were men!

Even more exciting is that “Latina” was the sixth-most-searched-for term from American Pornhub users in 2018, beating out “big ass,” “big tits,” and “anal.” So the good news is that if you’re a Latina stepmom MILF with big tits and a big ass who is into threesomes and anal, you can expect a lot of sex with white American men.

So, do white American males need sex at least once a week? I can’t say conclusively, but they certainly do have a huge amount of interest in sex, and I doubt that interest is purely platonic. Maybe the perceived lack of interest in sex has more to do with a lack of communication than a lack of desire. Usually, lack of communication about sex is the result of shame and guilt. If you can somehow create an environment where those don’t exist, you will be well fucked.

We were friends. Nothing more. Just two kids from Jersey traveling abroad who happened to bump into each other by stereotypical mistake. His White European friends dared him to go and talk to that Black Brazilian girl sitting on the beach, who was really a Black American girl in disguise. After listening to his tired pick up line in American-accented Portuguese, I cut him off and bluntly asked him in English where he was from. Shocked, he laughed and said, “I totally thought you were Brazilian.” He wouldn’t be the first to make the assumption.

Nonetheless, he invited me back to meet his friends, who were staring at him in disbelief thinking he’d actually succeeded in picking up this Brazilian girl. He broke the ice immediately and said, “She’s American.” And once again, I got the line, “We thought you were Brazilian!” After watching the sunset together, he invited me to meet up with them to salsa that evening. I wouldn’t give him a definite answer because I had articles to finish and work to do. But he was persistent and followed up by Skyping me that evening again extending his invitation. I still politely declined.

A few days later, he was headed to a nearby island and invited me to come along to explore. I was looking to get away from the city, so I accepted, of course, booking my own hotel room and arriving days late on my own schedule. We spent the following days hanging out, walking the beach, but still keeping things platonic. He had met and pursued a local Brasilian girl who was beyond sweet. And frankly, I just wouldn’t let my guard down to the idea of hooking up with a White American guy when there were so many Afro-Brazilian men in my surroundings. I was prejudiced, or in kinder words, had a preference for brown beautiful men.

Eventually, our vacation ended and he headed to the south of Brasil to start his new job. I returned to the city to continue living my life, and we kept in touch through semi-frequent Skype chats about our lives as Americans in Brazil. He told me to hit him up when I came to his city. And when I finally made the trip, I did. It had been almost six months since we had first met, and I certainly had changed.

I had opened a different chapter in my dating life, one that included more interracial dating than relationships with Black men in Brazil. So when we hung out, all of the sudden our platonic friendship transformed into a prospect, even though it had likely already been a prospect for him months back. I was sick, blowing my runny nose, and coughing, but he still wrapped his arms around me, made me tea, and made sure I was comfortable in his home.

What followed was a “first” to remember, as we took our time kissing and exploring each other’s bodies for the first time. While I know I wasn’t the first black woman he ever had sex with, he was the first White American that I had ever let into such an intimate space. Prior to that, I had shared my body with White Brasilians and Argentineans. But this was different. This made me feel like my growth had come full circle, as I struggled growing up in a predominately White Jersey suburb to feel like interracial dating was an option for a young Black woman. While young Black men certainly enjoyed relationships with young White women in my town, Black girls rarely were seen exploring the same types of relationships. Part of it was prejudice; part of it was reality. But the opportunities weren’t equal or treated the same.

I grew up believing a number of stereotypes about non-Black men, especially when it came to sex. If you asked most of my friends, their packages tended to be small unless they were of Latin or Italian descent, but they made up for it in the oral sex arena. So when I finally allowed myself to sexually enjoy and explore men of other races and cultures, I found these stereotypes blatantly untrue, just as several of the Black men that I had shared my body with didn’t live up to the Mandingo standard.

My first time with this White kid from Jersey was intense. The sex was focused primarily on my pleasure, and he wasn’t lacking in anyway to be able to deliver it. But it did make me reflect on why I had limited myself for so long to just having sex and dating Black men or never challenging the popular stereotypes.

Janice Rhoshalle Littlejohn, co-author of the soon-to-be released Swirling: How to Date, Mate, and Relate Mixing Race, Culture, and Creed, put it best in the chapter called, “Let’s Talk About Sex … and Stereotypes”:

“We think we have evolved into new-millennium modern-day thinkers, but black women all over the country, regardless of education and socioeconomic status, are living with age-old ideas when it comes to our consideration of the ideal sexual partner. We yearn to embrace our sexual bliss, and yet have allowed what our mothers, grandmothers, aunties, and sister-friends have said about “them” keep us from pursuing something new. We know how hard it is to fight against the stereotypes of black women as lascivious, innately promiscuous, and even predatory, deviants— and yet we feel more than justified in projecting our own labels on others, unfairly sizing up men and defining their capabilities between the sheets (or lack thereof) based on what so-and-so- said instead of considering the realities of the individual that just might be the guy who can makes your toes curl.”

My toes curled, more than once. I screamed, a few times. And even though I doubt me and this kid from Jersey will ever be more than just friends due to our chosen life paths (he’s ready to settle in one place and pursue a serious relationship, I want to keep traveling and find a partner who is willing to go with me), it was still worth giving us the opportunity to share intimacy, a deeper level of connection, and now, a stronger friendship.

I don’t know what color my husband will be, or what culture he’ll be from, but I will say this. It’s amazing what I’ve learned in life when I’m open to more than one possibility. I’m no longer limiting my options in love or sex.

Have you ever tried sex with someone outside your race and found it went against popular stereotypes? Did you enjoy yourself or did you want to ‘go back home’? Share your story.

Sex Tourism Isn’t Just for Straight White Guys Anymore

“If you’d told me back in 2017 that I’d spend the next two years visiting a host of different clothing-optional, adult-centric resorts, I probably wouldn’t have believed you,” said Simone Paget, a writer for the Toronto Sun in her 30s. “I’m the kind of person that doesn’t even like changing in public at the gym.”

But Paget is finding her planned sex travel experiences “liberating,” she said, after feeling out of place seeking queer sex at home. In her community, she said, “Biphobia is very real—people assume I’m ‘experimenting.’” About six months after coming out, she took her first solo trip to Temptation Cancun Resort, an adults-only hotel with topless-optional areas. Paget’s travel experiences allowed her to experiment with her sexuality on her terms. “I met other women like me who don’t necessarily feel the need to define their desires one way or another,” she said. “I could make out with a man one day and a woman the next, and literally no one cared. This was revelatory to me.”

Traveling for sex has traditionally been a pursuit reserved for wealthy, white, morally ambiguous men in search of sexual adventure with “exotic” foreigners, or in other cases, freshly divorced middle-aged white women. In recent years, growing numbers of women are traveling abroad, and many are traveling specifically for sex. Sex travelers are younger and queerer than ever before, they’re not all white, and many prefer to travel alone.

In finding their own avenues toward sexual liberation, these sex tourists are grappling with a practice that is traditionally colonialist, racist, and classist—and finding more ethical ways to travel while horny than soliciting sex workers in Asia, Africa, and the Caribbean, where sex tourism fuels local economies. Raquel Rosario Sanchez, a feminist writer and Ph.D. candidate with the Center for Gender and Violence Research at the University of Bristol explained that traditional sex tourism is often fueled by racial fetishism and imperialism. “You’re singling out a particular destination with the intention of paying locals for sex to satisfy a fetish,” she said. “That throws into the mix a whole set of dynamics which problematize an already unequal relationship.”

International tourism for any purpose, sexual or otherwise, can also be ethically dubious when it comes at such a high environmental and infrastructural cost to many areas of the Global South. While adult-oriented travel is no exception, navigating sex itself abroad with care and respect isn’t impossible. According to Sanchez, “The ethical way for a white tourist to navigate this issue is to have sex only with people who are sexually attracted to them, not with people who have to be coerced with money.” More ethical sex tourism also extends to thinking critically about fetishization. Before hooking up with anyone in a foreign country, Sanchez advised that sex tourists question any preconceived ideas they may have brought with them and examine their motivations for seeking sex abroad: “What is a Dominican woman supposed to do sexually that you cannot get from a consenting partner in Finland?”

Some resorts enforce strict boundaries regarding sexual consent and interactions between guests and staff with the goal of reducing any potential coercion or mistreatment from guests. “Creating a safe environment is crucial,” said Patric Loeser, General Manager of Temptation Cancun Resort, and that extends to guests’ treatment of employees. Loeser said all staff are thoroughly trained to reject any sexual advances from guests—and that some staff members are specifically employed to keep an eye out for any potential misconduct toward their colleagues. “Our ‘referees’ are always on the lookout ready to intercept guests behaving inappropriately, either towards other guests or staff members, by issuing time-outs,” she said.

Many adult destinations welcome guests of all sexual orientations, creating safer places for queer women to travel for sex. Twenty-seven-year-old NYC-based writer and Bi Girls Club founder Gabrielle Noelle, visited a Jamaican resort, Hedonism II, which regularly hosts LBGTQ travel groups, swingers’ parties, and festivals, last summer. “Everyone was so friendly and comfortable, it almost felt like another world,” Noelle said. “I felt a lot less feelings of shame or second-guessing came up.” Noelle also spent time in the resort’s “play room,” a designated area for couples, single women, and invited men to have sex—an experience she didn’t feel free to seek out at home.

Sometimes, though, Noelle felt tokenized as a bisexual woman among the many horny straight couples also visiting. “Whenever someone’s girlfriend tried to coerce me into a threesome, I got extra annoyed,” said Noelle. “A lot of bisexual women were present, but there was definitely a ‘unicorn’ culture.” Though lesbian-only resorts in the U.S. are practically extinct, those looking to avoid unicorn hunters may turn to membership organizations like Skirt Club, which hosts both casual meetups and sex parties for bisexual women in the U.S. and abroad.

Patrice J. Williams, a 30-year-old Black writer in New York, enjoys clothing-optional travel because she feels freer to wear—or take off—whatever she wants. “When I’m back home, I can be walking from the gym in sweats, but men still harass me. It was extremely comfortable knowing I could be totally naked and men wouldn’t assume I was providing an invitation for sex,” Williams told VICE about her visit to Hedonism II. Williams also spent time in the playroom, though she preferred to sit back and observe. That informed her encounters in general, she said: “My experience certainly made me more willing to openly express my curiosities and hear about other people’s lifestyles.”

Williams noted that some adult-oriented resorts can be overwhelmingly white. Even among other naked tourists, Williams worried about attracting unwanted attention as one of the few women of color at one of the resorts she visited. “Though my overall experience was great, at times I was hyper-aware of the white gaze, and that I was nude in front of people who had probably never seen a naked Black body before,” she said.

“As a Black woman, I have come to expect it,” said Bianca Lambert, a 33-year-old writer and actress in Los Angeles who also visited Hedonism II. “I have had white men say, ‘I’ve never dated a Black woman before,’ as if it’s some kind of compliment that they’re giving me a try,” she said. “Sometimes, words don’t even need to be said. You can feel it just in how people stare at you, especially my butt and hair,” Lambert said. “I give them a glance that says, I see you. Don’t say anything stupid, and keep it moving. If I took the time to address every person, I’d be exhausted, and as a Black woman, I am already tired.” Lambert pointed out that the specific experiences of Black women, LGBTQ people, and people of color more generally may still be industry-wide blind spots.

“Destinations can accommodate queer folks better by creating more specifically LGBTQ programming, teaching staff to use gender-inclusive language, and not specifically housing programming within a gender binary,” Noelle added. “They often referred to folks who ‘went both ways’ or suggested people liked men or women. Simply shifting their language to acknowledge many genders would be cool.”

Noelle recommended that other young travelers, especially those who aren’t straight or white, check resort schedules for queer- and POC-friendly events on offer at destinations. “Overall, I had a great time. I can only imagine how much more fun I would’ve had during a week that was populated with more young folks, folks of color, and bi+ folks,” Noelle said.

Regardless of where and with whom a person engages in sex travel, Sanchez said it’s imperative to approach potential partners with respect, not as novelties or commodities. “It’s tempting to visit a place with ideas branded in your mind about the people there and then look for evidence to confirm those ideas,” said Sanchez. “Women and men alike can be ethical sex tourists and ethical tourists in general by being willing to challenge their ideas, to always recognize the humanity in the other person.”

While the sentiment of “I’ve never measured my cock, I figure I couldn’t do anything about it anyway” is certainly better than an unreasonable obsession with size, I am more of a fan of know what you’ve got, and work it.

Penis size matters, but probably not in the way that most people think.

The saying “it’s not the size of the worm, it’s the way it wriggles” always gives me uncomfortable mental images, but the meaning is spot on. Size only matters because it tells you the way you ought to be wriggling.

The men who have measured seem to only go for length. In the conclusion of the Ansell Research study on penis size, they pointed out that in every study where medical professionals measured a man’s penis, average length was below six inches. Let men measure their own, and length jumps above six inches.

Now, I’m not claiming that a random person coming at you with a measuring tape isn’t going to be a little wilting, but it seems a little suspicious.

Women, on the other hand, really only notice length in the negative sense. Longer isn’t always better.

Certain positions, like doggy style, combined with a longer-than-average cock are likely to end with the girl being rammed in the cervix.

This is not a fun thing.

Making sure you spend time on foreplay is a good idea for everyone and can help avoid painful incidence if you are longer than average. When aroused, a woman’s vagina lengthens and the cervix retracts, which means there is more room for a longer cock than if the arousal process is truncated.

To start with, missionary tends to not irritate, and girl on top allows her to control angle and depth of penetration, as well as offering the best chance for orgasm in general. It’s in the more acrobatic positions that things get hairy.

If a position ends with your partner in pain, there are a few tricks to try. The first and easiest is to control how deeply you thrust. This may take more attention than you have in the midst of sex. The second option is to get a cock ring designed to keep you from penetrating as deeply. Cock rings add an element of technicality to the encounter, but they can allow a man to enjoy positions that would otherwise be off limits.

For men who trend in the other direction as far as length, from behind is a position that allows deep penetration along with access to both breasts and clitoris, so take advantage and she won’t be thinking of length at all.

In fact, she probably wouldn’t notice anyway. According to one penis size preference chart floating around the Internet, a chart from all appearances designed expressly to give men a size complex, the ideal length for a penis ranges from 7.25 to 8.5 inches. Considering the vast majority of penises are 5.5 to 6.3 inches, it seems like there must be a lot of disappointed women in the world. Not to mention the fact that things can get a little hairy as far as cervix bumping goes starting well short of 7 inches.

The reported preferred girth is 6 to 6.5 inches. Average is 4.9 inches, with the majority falling from 4.7 to 5.1 inches. To put that reported preferred girth in perspective, 6 inches is also the average size of a woman’s wrist. Given the rarity of the super large penis, it makes me wonder who exactly “The Authentic Woman’s Penis Size Preference Chart” was polling. I’m pretty inclined to just chalk it up to bad estimation skills.

That’s not to downplay the importance of girth. In fact, more women are going to speak positively of an above average girth than the super long penis that guys seem most concerned with.

But again, size isn’t king. The benefit of girth is that it makes it easier to get G-spot stimulation, no matter the position. If you don’t have that advantage, just concentrate on positions that have the penis rubbing against the front wall of the vagina. Putting a pillow under her hips during missionary can help keep her pelvis tilted and the fun bits in range.

In fact, most positions, with a little modification, can have any size penis rubbing the right way, and conversely, the wrong way too. Girth doesn’t get you out of knowing what you are doing.

And whether your partner thinks you are too big or too small, a dildo that fits size preference exactly can be used.

That is really what the whole size issue comes down to: preference. And orgasm washes that right out the window. Big, small or right in the middle of the pack, technique and care matter far more than something you really can’t do anything about.

Put down the rulers, guys — whether your penis is the “right” size depends on the proportions of the rest of your body, a new study finds.

Women rate men with larger penises more attractive, but the returns on bigger genitals start to decrease at a flaccid length of 2.99 inches (7.6 centimeters), the researchers found. What’s more, larger penises gave tall men a bigger attractiveness boost than shorter men. The study suggests that women’s preferences for bigger penises could explain why human males have relatively big genitals for their body size.

Studies on women’s preferences for penis size have been mixed, with some suggesting that women who frequently orgasm through vaginal stimulation are the pickiest, perhaps because penis size matters for that sort of stimulation. Men typically fret more about size than women, however, at least according to a 2007 review article in the British Journal of Urology International

But studies have relied on questionnaires, which may not always glean honest answers, Australian researchers wrote today (April 8) in the journal Proceedings of the National Academy of Sciences. And in other studies, scientists have asked women to judge the attractiveness of male figures in photos with only penis size varied, when in fact no trait is ever evaluated in a vacuum, the scientists added.

To compensate, the researchers, led by Michael Jennions of Australian National University, showed 105 young Australian women life-size computer-generated figures of nude men, varying the figures’ flaccid penis size, height and shoulder-to-hip ratio. Height and shoulder-to-hip ratio have previously been shown as factors used by women to judge attractiveness. The computer simulations varied penis width in sync with length, so that all penises were proportional.

The results revealed that women preferred taller men as well as high shoulder-to-hip ratios (meaning that the wider the shoulders were than the hip, the more attractive the man). Shoulder-to-hip ratio was a major determiner of attractiveness, accounting for 79.6 percent of the variation in hot-or-not ratings.

Though the effect was less extreme, women also preferred larger penises, at least up to 5.1 inches (13 cm) flaccid, which was the largest computer-generated penis in the study. Beyond 2.99 inches, however, the additional attractiveness per extra length started to decline. That’s good news for guys, according to a 2001 Italian study that found 2.99 inches flaccid to be below average.

When the researchers controlled for shoulder-to-hip ratio, they found that a larger penis had a greater effect on attractiveness for taller men. It’s possible that a larger penis just looked more proportional on a taller man’s body, the researchers wrote, or it could be that women were biased against shorter men to the extent that even large genitals didn’t help.

Women’s own features mattered as well, the researchers found: Taller women were more likely to find taller men attractive. Women with greater body mass per height were slightly more likely than thinner women to weigh penis size more heavily in their judgments of attractiveness, though the difference was small.

The findings might help explain why humans have remarkably large genitalia given their average body size, the researchers wrote. Male humans outgun any other primate species: For example, male gorillas can weigh as much as 400 pounds (180 kilograms), but their erect penis length is only about 1.5 inches (4 cm). Human males weigh about half of what gorillas do, but studies peg average erect or flaccid-but-stretched penis length from 4.7 inches (12 cm) to 6.5 inches (16.7 cm).

Evolutionary biologists theorize that large human penises might help remove sperm from competing males during sex, but in an era before clothing, women may have been drawn to mating with men whose genitalia caught their eye. Men with larger penises, then, may have passed on their genes more readily, resulting in the large-genitals trait being handed down the generations. In other words, guys may have women to thank for their greater-than-gorilla-sized genitals.
