I'm a huge fan of the yearly TED conference. I've spent many hours watching fascinating talks on how fungus is going to save the world, what exactly it is that the right half the brain does, and much much more. If you haven't browsed the website and watched a few talks, I highly recommend it.I was surprised to see that I had missed a talk this past February from Mary Roach about orgasms! Roach is the author of Bonk: The Curious Coupling of Science and Sex, which is all about the science of sexuality and has some amazing information in it.Here is Roach's TED talk on orgasms. From stimulating pigs to the distance semen can travel, I gaurantee you'll learn something.
