To me this paints a different picture. As opposed to the idea that young sex causes what i call anti social behavoir, is it not perfectly reasonable to suggest that the naughty one's get more girlfirneds? The well behaved or quiet one's don't get girlfriends untill their older anyway. There are too many other factors in a youing persons life that could affect their behavoir, so i conclude that this argument is logically flawed. That or the person who wrote it is a bitter 40 year old virgin.
