Unless they're in a committed and happy relationship, women tend to (tend to, I said) need multiple reasons for hopping in the sack with a lover. These reasons usually just manifest themselves into an overall feeling of yes or no, but the point is that it's so much more complicated than men, who usually just cite "sex" as the reason for…WANTING TO HAVE SEX. That's a head-scratcher, I know.

But, if women only knew the health benefits sex has to offer, then maybe their sex drive wouldn't drop off while their boyfriends are still at 18-year-old levels. Someone should make a guide to be shared with all sexually active women-folk. Oh, wait someone's already done that? Yes it’s true, and you're reading it.

Just keep in mind that if you’re a selfish or inept lover, then this won’t do much good for your girl (i.e. she’s going to need to magna cum laude to enjoy the benefits detailed below). What are you waiting for? Spread the gospel!
