I have a couple books on sex, I have been known to trot these out to point out the reality.
Frankly, once a man has fallen for the fiction of porn, they are almost beyond help.
I also find men who are the male version of whores really distasteful. I don't even bother with them because where making love is concerned, we are speaking a completely different language, he is shaking hands, I am giving a part of my heart, NOT THE SAME THING.
