16 Penis Facts That Will Shock You

We’re penis obsessed. There are no two ways about it. Phallic imagery follows us wherever we go, and if there’s anything men think about more than sex, it’s their penis. Can you break your penis? Who has the world’s largest penis? What are some fun facts about the penis?

We’ve gathered your most asked cock-questions and found the answers. Here are 16 penis facts you’ve always wanted to know.

16 fun facts about the penis: Get familiar with your favorite organ.

1. The average penis size is 5-6 inches erect.

And 3-4 inches flaccid. Penis-owners also worry about the size of their anatomy way more than they should. Dick facts research shows that people care more about what a penis can do than how it measures. If you remember any of these fun facts about the penis, make sure you remember this!

2. The world’s largest penis? 19 inches.

The man this titan belongs to, however, admitted to spending his life stretching his penis. The man known to be in second place has a penis 13.5 inches when erect. Remember, this is supposed to be fun facts about the penis - this is far from the average penis size, so stop looking down and feeling sad.

This came to public attention when his “suspicious-looking package” caused a scare at airport security… We’re just as shocked as you are.

3. Pornstar penis facts: The average is 8 inches long erect.

Which is actually not much bigger than the average! Some porn stars are way above this, but remember that they are the exception, not the norm. Dick facts for dummies: Porn penises are not the same as real ones.

4. Can you break your penis? Not properly but… enough.

A penis can’t be “broken” like your wrist or foot can because there’s no bone in it. But that doesn’t mean it’s shatterproof! There is such a thing as a “penile fracture” which will turn a member blue.

And if a penis is twisted too much, the tubes that fill with blood when it’s erect can burst and cause significant pain and swelling. So don’t twist too much - it’s not an actual magic wand.

5. Is the penis a muscle? Nope.

The famous “love muscle” is, in fact, not a muscle at all. The penis is made up mostly of spongy tissue that fills with blood when the person gets an erection. What allows penises to move for penetration and urination are the muscles around it.

You might have to stop calling it “The Love Muscle”. Sorry.

6. And what is a boner, anyway?

Your brain, blood vessels, hormones, nerves, tissues, and psyche all work together to produce a boner. The penis has 2 cylinder-shaped chambers that fill with blood when you get a boner, which makes the penis swell and harden.

This swelling blocks the veins that usually remove blood from the penis, so the blood stays there until the erection goes away.

7. What does “grower vs shower” actually mean?

“Showers” are penises without surprises. With Showers, the length and girth you see when flaccid is similar to what you get when erect. Showers have less elastin and more collagen, which makes them less stretchy.

“Growers” are like surprise birthday presents. They may seem on the smaller side when soft, but due to their high levels of elastin, their size can increase drastically (sometimes doubling) when they get hard.

8. When does the penis stop growing? 5 years after puberty starts.

Boys usually start puberty between 9 and 14, and it lasts for around 5 years. For the most part, your penis won’t grow any bigger once you reach 18 or 19. Hoping for a different answer? We’re just here to give the dick facts, I’m afraid.

9. The world’s smallest penis: ⅝ of an inch.

An anonymous man won the smallest penis contest with this humble-sized horn. Just less than 1% of the male population has a micropenis, where most of the penis is inside rather than outside the body.

Speaking of contests, the Smallest Penis Brooklyn Contest is an annual event that draws in surprisingly big, rowdy crowds. Where do we sign up?

10. Does masturbating make your penis smaller? No!

No. No.

11. They can be surprisingly bendy.

Apparently the penis has the potential to curve into a boomerang shape if a penis-owner has sex with a woman in the missionary position. Out of all penis facts, is this terrifying or wonderful?

12. Fun facts about the penis: Cum is full of sperm (more so than we thought).

A single ejaculation can produce between 40 million and 1.2 billion sperm cells. If you needed any incentive to use protection, this might be it.

13. Shocking penis facts: Some men are born with two penises.

It’s is a condition called Diphallus and around 100 men have it worldwide, in other words, 1 in every 5 to 6 million male births. Some snakes and lizards have hemipenes, which is essentially a two-headed penis.

14. Men have an average number of 11 erections per day.

They also experience on average 4 to 5 erections during a night’s sleep, which typically lasts for 25 minutes. That’s a whole lot of time spent erect.

15. The average number of times a man will ejaculate in his lifetime: 7,200.

And the average speed of ejaculation is 28 miles an hour. Can you imagine a future time in which men compare ejaculation speed, not average penis size? Someone could lose an eye.

16. Ejaculation also has nothing to do with the brain. Surprised?

We’re not either. If these penis facts are just telling you what you already know - sorry. Ejaculation is actually controlled and stimulated by the spinal chord, which is what causes the uncontrollable-orgasm-squirming that sometimes happens during sex.
