20 Misconceptions About Sex

Hi, I’m Aaron Carroll. You might know me from Healthcare Triage, but today I’m diving into a different topic over at Mental Floss. We’re going to explore 20 common myths and misconceptions about sex. If this topic isn’t for you, feel free to skip this one.

Myth 1: Shoe Size and Penis Size Are Linked

It’s a popular belief that a man’s shoe size can indicate his penis size. However, numerous studies have shown no connection between the two. Similarly, there’s no correlation between penis size and the size of a man’s hands, ears, or any other body part. Shoe size only reflects one’s preference in footwear.

Myth 2: The Average Penis Size is 7 Inches

Contrary to popular belief, the average penis size is not 7 inches. Research involving 15 studies on stretched penile length found the average to be around 5 inches. For instance, the Kinsey Institute’s study of over 1,600 men revealed an average erect size of about 5.6 inches. Interestingly, erections from oral sex tend to be larger than those from manual stimulation, though the reason remains unclear.

Myth 3: Condoms Make You Last Longer

Some believe that wearing a condom can prolong sexual activity. However, a study involving 500 men from Europe and America found that the average time before ejaculation was about 5.4 minutes, with no significant difference when using a condom.

Myth 4: You Can Significantly Increase Ejaculate Volume

It’s a misconception that you can greatly increase your ejaculate volume. A 2005 study of over 6,000 men showed that those who abstained for a week had an average volume of 3.7 milliliters, compared to 2.3 milliliters for those who had sex the day before. The difference is minimal.

Myth 5: Men Prefer Blondes

While some studies suggest men prefer blondes, these often come from regions where blonde hair is less common. In areas where blonde hair is more prevalent, preferences are less distinct.

Myth 6: Most Women Are Hairless

It’s a myth that most women remove all their body hair. A 2010 survey found that only 11% of women aged 18 to 68 remove all their hair most of the time, while 20% do not remove any hair at all.

Myth 7: Bigger Breasts Are Less Sensitive

There’s a belief that larger breasts are less sensitive than smaller ones. While studies show differences in sensitivity, no woman has defined sensitivity during sex as the ability to feel a single hair.

Myth 8: Sex is Great Exercise

While sex does burn some calories, the average duration of sexual activity is not long enough to be considered a significant workout.

Myth 9: All Men Cheat More Than Women

It’s a misconception that all men cheat more than women. If cheating is defined strictly as intercourse, men do cheat more often. However, when the definition is broadened, women cheat almost as frequently as men.

Myth 10: Men Peak Sexually Before Women

There’s a myth that men reach their sexual peak long before women. If “peak” is defined by frequency of sex, both men and women may experience long periods without it during their 20s.

Myth 11: Young Men Are More Likely to Ejaculate Prematurely

Premature ejaculation is often thought to be more common in young men, but studies show it affects men across various age groups.

Myth 12: Men Think About Sex Every 7 Seconds

It’s a myth that men think about sex every 7 seconds. Many men report thinking about sex only a few times a month or a few times a week.

Myth 13: Married People Don’t Masturbate

Contrary to popular belief, married individuals do masturbate. Studies indicate that a significant percentage of both men and women have masturbated in the past year.

Myth 14: Dead Males Can Develop Erections

While it’s possible to die with an erection, a dead body cannot ejaculate.

Myth 15: Only Males Have Wet Dreams

It’s a misconception that only males experience wet dreams. Studies show that a significant percentage of females report having them as well.

Myth 16: Masturbating Causes Blindness

The idea that masturbation can cause blindness is completely false.

Myth 17: Birth Control Pills Cause Weight Gain

It’s a myth that birth control pills lead to weight gain. A meta-analysis found no evidence supporting this claim.

Myth 18: You Can Influence Your Baby’s Sex

The belief that you can determine your baby’s sex through specific sexual practices is unfounded. The idea that X sperm are larger than Y sperm lacks evidence.

Myth 19: HPV Vaccine is Only Needed When You’re Sexually Active

It’s crucial to get the HPV vaccine before exposure to the virus for it to be effective, not just when you’re sexually active.

Here’s a sanitized version of the YouTube transcript:

Hi, I’m Aaron Carroll. You can usually find me here at Healthcare Triage, but today we’re heading over to the salon for Mental Floss, where I’ll be discussing 20 myths and misconceptions about sex. Fair warning: this episode is about sex. If you think that’s inappropriate or it’s not your thing, it might be a good idea to turn this off now.

Did you know that it’s a myth that there’s any correlation between penis size and shoe size? Many studies have been conducted, and they fail to find any link between the size of a man’s shoes and the size of his penis. There’s also no relationship between penis size and the size of his hands, ears, or anything else. Looking at someone’s shoes will only tell you about their taste in footwear.

It’s also a myth that the average man has a 7-inch penis. To study this correctly, you can’t just ask men how big their penises are; you have to measure them. We found 15 studies that looked at stretched penile length, and most of them had an average around 5 inches. For example, the Kinsey Institute studied more than 1,600 men and found that the average erect penis size was about 5.6 inches. Interestingly, erections brought about by oral sex were larger than those brought about by manual stimulation, but we don’t know why.

Another myth is that wearing a condom makes you last longer. A study of 500 men from Europe and America found that the average time before ejaculation was about 5.4 minutes, with no significant difference when wearing a condom.

It’s also a myth that you can build up a much bigger ejaculate. A 2005 study of more than 6,000 men found that those who waited a week had an average ejaculate volume of 3.7 milliliters, while those who had sex the day before had a volume of 2.3 milliliters. The difference is minimal.

There’s a misconception that men prefer blondes over brunettes. While some studies suggest this, they often come from areas where blonde hair is less common. In places where blonde hair is more prevalent, preferences are less clear.

It’s also a myth that most women are going hairless these days. A 2010 survey found that only 11% of women aged 18 to 68 remove all of their hair most of the time, while 20% remove no hair at all.

Another myth is that bigger breasts are less sensitive than smaller breasts. Studies have shown differences in sensitivity, but no woman has defined sensitivity during sex as the ability to feel a single hair.

It’s a myth that sex is great exercise. While it burns some calories, the average time spent on sexual activity is not long enough to be considered a significant workout.

There’s also a misconception that all men cheat or that there’s a difference between men and women in terms of infidelity. If cheating is defined as intercourse, then yes, men cheat more often. However, if you broaden the definition, women cheat almost as often as men.

It’s a myth that men peak sexually long before women. If we define “peak” by frequency of sex, both men and women may go without it for long periods during their 20s.

Another myth is that young men are more likely to ejaculate prematurely. Studies show that this issue affects men across various age groups.

It’s also a myth that men think about sex every 7 seconds. Many men report thinking about sex only a few times a month or a few times a week.

Married people also do masturbate. Studies show that a significant percentage of both men and women report having masturbated in the past year.

It’s a myth that dead males can develop erections. While it’s possible to die with an erection, a dead body cannot ejaculate.

Another misconception is that only males have wet dreams. Studies show that a significant percentage of females report having experienced this as well.

It’s also a myth that masturbating will make you go blind. This is completely untrue.

Regarding birth control, it’s a myth that the pill makes you gain weight. A meta-analysis found no evidence that birth control pills cause weight gain.

It’s also a myth that you can influence the sex of your baby by how you have sex. The idea that X sperm are bigger than Y sperm is not supported by evidence.

Lastly, it’s a myth that you don’t need the HPV vaccine until you’re having sex. It’s important to get vaccinated before exposure to HPV for it to be effective.
