Men looking at women vs. women looking at men?

Personally I don't do it, I find it really embarrassing when women do this. It seems to be some kind of competition to keep up with men. I suppose this is a bit hypocritical but I am more steeled to male sexism, if I hear a man make a crude comment about a woman I tend to think 'you d!ckhead' and walk away, when the boot is on the other foot it's a bit more difficult, if I am supposed to be on a night out with mainly women and this is the main topic of conversation I get bored.
