Usually, when women talk about how they like confidence in a man, I think back to the sort of guys I've seen women drool over, and what they call confidence is basically something like a sort of virile snottiness; a combination of masculinity, aggression and superiority that I personally find extremely unpalatable. This nastiness is commonly found in various popular, successful or powerful men. I suspect it's where the whole "You find me repulsive, don't you?" thing comes from. They know.
