Here's another difference between men and women: men's state of sexual arousal matches their brain and their body pretty well, while women's sexual response is less consistent between what the head and the crotch are doing. I'll have to admit, though, any guy who's got a boner but his brain isn't thinking sexy thoughts had better talk to his doctor, something ain't right. Women, on the other hand, need to do a bit more, er, "inner reflection" to know what's going on down there. I, for one, volunteer to help with the examination. Don't worry, you'll know exactly what I'm thinking.
