Well i read an interesting article on yahoo shine it entales a man explaining how woman need to understand that everytime they have sex with a woman it doesn't = relationship! Well here a little excerpt
( Bottom line from a man--if i sleep with a woman i dont know or care about SEX is not going to make me care. (I stopped doing that years ago) That kind of sex is like scratching an itch. Once a man scratches, he's through. He aint sitting around thinking about that spot that itched or how good it felt scratching it. He's moving on with his life until tht spot itches again and it dont matter which hand scratches it with, just as long as he gets rid of the itch).
