Completely Bizarre Things BuzzFeed Taught Us About Sex

Sure, there are countless words for getting it on, but very few of them could be described as "classy." Thankfully BuzzFeed has rounded-up some lesser-known adjectives, nouns, and verbs to take the place of our usual crass euphemisms and romance-novel descriptors. For instance, did you now that "perfectly shaped buttocks" can be described as callipygian? Sounds a lot nicer than "nice ass," doesn't it? Or that "the bobbing or jiggling of a woman's breasts when she walks, dances, or exercises" is known as mammaquatia? No, you probably didn't.

Though this video isn't strictly sexual, it does explain why our private parts are covered in hair while the rest of our body is bald (it has to do with knowing when someone is sexually mature.) Another interesting fact: We have the same number of hair follicles as apes.

Nipples! They're weirder than you think! For instance, did you know that some people can achieve orgasm solely through nipple stimulation? Or that nipples form on the body in utero—before sex is even determined?

Watch as women comment on the advice given by an anonymous men's magazine. Some of the hilariously awful suggestions include putting your penis inside a woman and then remaining motionless and letting champagne bubble around a woman's clitoris.

Most of us have been in that awkward situation when we bring someone home from a long night out, but haven't yet made it to the bedroom (or couch). You know what's going to happen. He or she wants the same thing, but there are still those pesky social pretenses that have to be accounted for. This video eloquently displays that awkwardness. The takeaway: this is no time for small talk. Drop the facade and drop your pants.

There's no single activity that makes for a good relationship, but this video does a nice job covering the basic things a couple needs to do to stay connected, like give your partner a hug when they come in the room and hold hands when you walk down the street. Oh, and don't forget to have lots of sex.

Even where you're fully clothed, there are many subtle things a guy can do to attract women. (And behaviors women find sexy, that you might not have realized.) Something as simple as rolling up your shirtsleeves sends the message that you are ready for something more than friendship. Watch and learn how to sensually scratch your beard or get attention with the "save the last dance lean."

First thing's first. The facts in this video are disgusting, but they're also pretty clever. For instance, "When two people kiss...they create a really long tube with assholes at both ends." It's obvious if you think about it. But then again, why would you?

More than 50% of the world's population has a vagina, and yet they are often seen as veiled in mystery, even to their owners. In this video, BuzzFeed rounds up some interesting facts about the vulva, clitorises, and labia that should please both vagina-havers and fans. For instance, a vagina can expand 200% during sex or childbirth. There's also a tidbit about the similarities between vaginae and sharks.
