The women are initially attracted to the confidence a "bad boy" exudes. Confidence, is one of the most attractive features to a woman (or so I'm told, and have ascertained from study). If a man doesnt have much personal baggage (or rather, doesnt appear to) and holds himself in a powerful light, then the woman will ALSO hold him in that light. In short, women will see men how the MAN sees himself. At least initially. Over time relationships alter, and personalities and ..problems, expose themselves. But the reason for the inital contact, is because of the attractiveness of confidence. Men, who think (especially at that age) in short term, see this as a series of victories. Boys then pretend that long term relationships are anathma to prowess. Its about power, and its about fertility, and its about psychology. All of which leads to the ineviditable conclusion of emotional turmoil.
God granted us reason, but he didnt necessarily make it work with instincts.
