Hi, I'm Aaron Carroll. You can usually find me here at Healthcare Triage,

but today we're going to head over to the salon for, Mental Floss

未来進行形

where I'll be talking to you about 20 myths and misconceptions about sex.

This is an episode about sex. If you think that's inappropriate or it's not

your thing, probably a good idea to turn this off now.

Did you know that it's a myth there's any correlation between penis between penis size and shoe size?

There have been many studies on this, amazingly enough and they failed to find

any link between the size of a man's shoes and the size of a man's stretched or erect penis.

There's also no relationship between his penis and the size of his hands or ears.

Or anything else for that matter. Looking at his shoes will only tell you about his taste in footwear.

And that's the first of many misconceptions about sex I'm gonna debunk today.

It's a myth that the average man has a seven inch penis.

Let's be honest, to study this correctly you can't ask man how big their penises are,

you have to get in there and measure yourself.

We found 15 studies that looked at scratched penile length and most men had

Here in Indiana, the Kinsey Institute studied more than 1,600 men

and found an average erect penis size was about 5.6 inches.

Interestingly, erections brought about by oral sex were larger than

erections brought about by manual stimulation.

Is that cuz oral sex causes bigger erections,

or is it cuz bigger penises get oral sex? We have no idea.

It's a myth that wearing a condom makes you last longer.

In a study of 500 men from Europe and America,

their "intravaginal ejaculation latency time" was 5.4 minutes.

They literally clocked these men with a stopwatch.

Men, 18-30 years old lasted the longest, at 6.5 minutes on average.

Dropping to only 4.3 minutes for men over 51.

Wearing a condom made no difference. Nor did whether the men were circumcised.

Here Clark Kent's SuperSpeed backfires, Aquaman wins.

It's a myth that you can build up on much bigger load.

I'm not sure why so many people care about this but here we go.

In 2005, a study of more than 6,000 men who provided about 9,500 "samples" was published.

Men who waited a week had an average ejaculate volume of 3.7 ml.

Men who had sex the day before, had a volume of 2.3 ml.

That's a difference of less than 1/3 of a teaspoon.

But even men who came earlier that day still produced 2.4 ml,

so we can't imagine that waiting is worth it.

It's a myth that men want blondes more than brunettes.

Sure, there've been some local studies that point to the fact that men may say this.

But they're usually in places were blonde hair is less common.

In areas where blonde hair is more common, the preference is not as clear.

There's also no correlation in studies between women having blonde hair

and having more sexual partners, more sex, or more orgasms.

It's a myth that most women are going hairless these days.

Yes, it's true that Playboy centerfolds are more likely to have little or no pubic hair in recent years,

found that only 11% of women age 18-68 remove all of their hair most of the time.

and only about a quarter removed their pubic hair some of the time.

with 21% of 18-24 year olds shaving it all off

versus 9% of women in their 30's or 2% of women over 50.

Bottom line though, is that the majority of women of all ages

It's a myth that bigger breasts are less sensitive than smaller breasts.

Some people have argued that bigger breasts have longer nerves to get to the skin,

and that this makes them "feel" less.  Of course, then, taller women would have less sensitivity, too,

that ask women if they could feel hair-like filaments of different sizes on their breasts.

but no woman ever defined sensitivity during sex as the ability to feel a single hair.

Besides, no one argues that men with smaller penises

derive more pleasure than men with large penises.

Yeah, it burns off some calories but most people aren't active for that long.

30 minutes of sex might burn off 85-150 calories

but remember the average intravaginal ejaculation latency time I mentioned before?

Not even close. The time that sex is aerobic

where your heart rate goes up is even shorter.

Despite what you've learned from our highly scientific competitor, Mad Men

it's a myth that all men cheat or that there's a difference between men and women

If you define cheating as intercourse then yeah men cheat more often.

If you broaden it to include other acts, then women cheat pretty much as often as men

Surprisingly, age doesn't seem to be a factor, either.

The most comprehensive study we've seen showed that 23% of men,

and 19% of women, had cheated in their current relationship.

The biggest predictor was being unhappy or incompatible in terms of sexual attitudes or values.

It's a myth that men peak sexually long before women.

What does peak mean, anyway? If you define it to be the frequency of sex,

then both men and women are likely to go without it for a whole year during their 20's.

If we define it by masturbation, they're both most likely to do it in their late 20's.

If we define it by oral sex, men are most likely to get in their late twenties and

Women are most likely to give and receive it in their late 20's.

If we define sex at least four times a week, it's 30's or 40's for men,

and late 20's for women. There's no metric that makes this myth true.

Speaking of sexual peaks, did you ever wonder if Spiderman was a metaphor for going

It's a myth that young men are more likely to ejaculate prematurely.

If we define that as climaxing too early then studies have shown that

30% of 18-29 year olds have an issue. But so do 32% of men in their 30's,

28% of men in their 40's and 32% of men in their 50's.

For most men, it's a transient issue that goes away.

For men with severe and lifelong premature ejaculation,

It's a myth that men think about sex every 7 seconds. This one defies belief,
