This is your brain on girls

Apparently, lesbians' brains work more like straight men's brains than straight women's brains.

• Lesbians' brains reacted somewhat, though not completely, like those of heterosexual men, a team of Swedish researchers said in Tuesday's edition of Proceedings of the National Academy of Sciences.

While a lot of people would use this as evidence that lesbianism is, in fact, a matter of genetics (it is, by the way), I think this has a much simpler solution: there is a part of the brain that says, "OMG I LOVE VAGINA!!!!!!" Yes, it's that excitable.
