There's another "mentality" side to this issue. It seems that the porn community generally feels that the language used in porn flicks is really what sex is about. Every woman in these movies screams "FUCK ME! HARDER HARDER!", waking good neighbors three blocks around.
I have made love with numerous women (yes, I've been called a slut) and none have talked, or wanted talk like that.
On the other hand, I also feel that if you screw somebody over, you deserve to be called a slut. Gender notwithstanding!
Bottom line... Good women are gems to be cherished.
