The sexual harassment charges keep pouring in...

Men are going to behave that way when they're interacting with women no matter how socially taboo we make it, including making it illegal.  People regularly do socially taboo and illegal things.  And this is something that men are driven to do as much as any drug addict is driven to acquire and imbibe their drug of choice.  So women would more easily avoid situations they do not want to be in by assuming that any arbitrary man probably wants to have sex with them, and probably will hit on them (that's most men), possibly will try to touch/grope/etc. them (thats fewer, but you're not going to be able to predict which ones), and so on, in certain situations (such as being alone with the man in question).
