My little theory must be true because the last time I said this I got no arguments from women.
GUYS: The Key to women
A lot of guys get stuck in the "friend zone" with women they like and are often confused about why some men get to date a woman and some are just friends.
I have recently figured out the difference between the lover and the friend. Basically it is this:
The Lover will only stick around provided the woman is willing to sleep with him (and she knows this). The FRIEND will stick around no matter what in hopes of getting sex later (and she knows this). So she never gives the FRIEND sex because she doesn't have to in order to keep him.
