For many, finding a creative idiom for sex is almost as fun as the act. The birds and the bees, making love, hooking up, whoopie. These colorful terms coined over time describe one thing about humankind that we are absolutely sure of: People always have been, and will more than likely always will be, having sex. And although mainstream culture may make sex seem like a pretty cut-and-dry act, there are a lot of powerful mental and physiological forces at work to make the magic happen. So, what are the biological and psychological origins of sexual attraction? How did the cavemen do it? Does "bow-chicka-wow-wow" really play in the background?

Once you think you've mastered the basics, keep exploring to see what's in store for the future of sex. Spoiler alert: It involves robots. Let this playlist fill you in on the history of sex and uncover yet unseen sexual possibilities. Be warned, you might giggle once or twice.
