Sex

Sex and sexuality is about more than just two people, a bed, and a few aphrodisiacs. Scientists study why humans have sexual intercourse (it is good for you and good for the species) and how sex is driven by evolution, genes, emotions and more. There is also much to learn about the differing roles of men and women in the whole mating game. Yes, there's lots of science to explore. Not that an aphrodisiac isn't more fun.
