I had the pleasure of going out to a night club with a real man-whore the other night and since then I have had a foul taste in my mouth regarding the scene. I saw that he knew every guy. I would say things like "oh, he's cute" or "look at the arms on that one" and almost always he would say that he had slept with each guy. I don't want to be that. Just imagine what they all thought of him.
So, I have decided (this was days ago, and I am proud to say I am successful) in being anything but a slut. I am not going to give my number to anyone for a while.
Moral: you can learn from other's mistakes.
