Scientifically NSFW

So this dude found 8 couples to fuck in an MRI machine to photograph/film what, from an anatomical perspective, sex actually looks like. Awesome. I love this guy, I love everything he stands for, I love his use of science. The first part of this video explains who he is and what he's about. The good stuff starts around 1:30.
Warning to those who don't like reality: PENIS ALL UP IN YOUR GUTZ!
