The 37 most astounding facts about sex you’ll ever read
Human and animal biology offers a variety of unexpected details. From ancient inventions to the mechanics of the natural world, the reality of reproduction is often stranger than fiction.
These are 37 facts about sex that challenge common assumptions.
Historical and human facts
- Cleopatra is credited with the invention of the vibrator. She reportedly placed agitated insects inside a hollow sphere to create vibration.
- The clitoris extends 9cm under the skin.
- The average erection contains enough blood to keep three gerbils alive.
- Four popes have died during sex.
- The average human sperm cell contains about 37.5Mb of genetic data. An orgasm transfers roughly 1.5Gb of data in three seconds. This data transfer rate is millions of times faster than an average internet connection.
- About 100 million couples have sex every day. This means 65,000 couples are having sex right now.
- Human males ejaculate at 27mph.
- A woman’s breasts increase in size by up to 25% when she is sexually aroused.
- If your parents had waited five seconds later or started five seconds earlier you would not exist.
- The clitoris is anatomically synonymous with the male penis but lacks a urethra.
- Make-up simulates a woman’s face during orgasm. Lipstick mimics blood engorgement in the lips. Blush mimics flushed skin. Eyeliner makes eyes appear half closed.
- Red underwear is considered sexy as an evolutionary callback to when primate rumps became red during fertility cycles.
- In Victorian times, “blowsy” was slang for a prostitute. “Blow” was slang for ejaculation. By the 1930s, fellatio became known as a blow job. In Ancient Greece, the slang was “playing the flute”.
- Women may be louder during sex to attract other males from an evolutionary standpoint. Men are evolutionarily wired to be more aroused if they believe a woman has had sex recently.
- An Intel survey found 46% of American women would give up sex for two weeks rather than lose internet access.
- Lisa Sparks holds the record for having sex with 919 men in 24 hours. This is roughly 38 men per hour.
Animal kingdom mechanics
- French bulldogs cannot reproduce naturally because they are too top heavy. Every puppy is born via artificial insemination.
- Amazon River Dolphins are the only species recorded engaging in nasal sex.
- Opossums have a double-headed penis.
- Kangaroos have three vaginas.
- Female hyenas have clitorises that extend seven inches and serve as pseudopenises and birth canals.
- The blue whale ejaculates about 200 gallons of semen.
- Pigs orgasm for 30 minutes.
- Alligators have erections for 100% of their lives.
- The antechinus, an Australian rodent, has sex for 24 hours until the males die of exhaustion.
- Tapirs have an elbow in their penises.
- The barnacle has the largest penis in the animal kingdom by body mass percentage. It is often more than 50% of their soft tissue.
- Banana slugs sometimes get stuck during sex. They take turns nibbling the penis until they are free.
- The right whale has the largest testes in the world. They weigh half a ton.
- A grasshopper loses 1/3 of its body mass when it ejaculates.
- Penguins only orgasm once a year.
- The male praying mantis has a second brain in his bottom. This allows him to continue sex while the female eats his head.
- A full-grown female blue whale has a clitoris three feet long.
Did Colin Mochrie write this article? so much animal genitalia……
I don’t think I believe number 19.
Haha, burn dumbass
Lol, number 19 is eminently believable! It takes hundreds of sperm using the tiny bit of acid in the head of their bodies to breach the cell membrane of the ovum. Once a spot is weak enough, the next sperm to attack that spot breaks through and wins… game over!
If there were even a one second difference in time, either way, when the male orgasm occurred it very easily could’ve been another completely different sperm that made it into that one weak spot. Or maybe another sperm gets through at another spot first if ejaculation occurs later.
You are the product of a HUGE number of coincidental actions that just ‘happened’ to fall exactly right for you to be who you are! Not just the sperm/egg thing but the entire life history of both of your parents, your grandparents and on and on. And understand that the actions of those people were influenced and directed by their interactions with others that lasted their entire lives!
Talk about a mind-trip though experiment! Whoo!
Marriage is nothing but sex is everything
Marriage is nothing; butt sex is everything.
Marriage is only for cuckolds and have bastards .-
Who came first the chicken or the egg, duh the Rooster came first.

Your web site offered us with valuable information to work on. You have done an impressive job
and our whole community will be thankful to you.
Howdy! I could have sworn I’ve been to this web site before but after browsing through some of the articles I realized it’s new to me.
Nonetheless, I’m definitely delighted I came across it and I’ll be bookmarking it and checking
back often!
my blog post; livres pdf
Oh my fucking god u people actually think that fucking a bunch of sluts is better than a truthfull marriage!? Ur so sick, harun! Yea thats right I read harun’s tweet! :p
@Emma: You’re surprised?
8 this is awesome
How things have changed since Cleopatra ….
they should add at the end of #7 “with boys”
just one say,, uwoooww :D
Just wow!
#22 about missionary being the only legal position in Florida is bullshit theres no way thats true
I always thought it was gross if a woman recently had sex with another man. If I had to choose between two equally attractive women, I’d choose the woman that hasn’t had sex recently. That contradicts number 29.
15 and 18 are truly insane!
Ohhh!!!! Just wow!
wow… 319 men an hour….??? jeez how horny could one truly be
Interesting! Some of those facts are difficult to believe.
Too much infos regarding sex for today

Some cool stuff to know and some weird stuff that i didn’t care to know also I don’t don’t believe the one about Florida that just sounds stupid and completely false how could you be prosecuted for something like that could you imagine if people were just going down to police station and turning themselves in for having sex in positions other than missionary lol…….come on!!! that’s ridiculous

Not Florida.
Also I think Vibrators are outlawed there as well.
But not vibrators with bugs in them.
Pigs Orgasm for 30 minutes?!
Nice research you have done. Good Job.
