Never forget that men are pigs. The fact that you menstruate makes it okay to bitch as much as you want about anything you want. Criticize every other woman behind her back. Never reveal the full extent of your intelligence to a man. It's even okay to claim that you can't pump gasoline or check the oil.
Helpless females make a guy feel macho.
If a guy really cares about you, he should be able to read your mind. You needn't have to explain yourself, ever. And he should know what's expected of him without you saying anything. Be a tease. Men always want to know how they compare to the last guy you were with.
