Do good girls like bad boys and assholes?

This has been told to me before and I think that it seems to be somewhat of a Myth and over stereotyped by Holywood and TV shows based on what I see. I'm a good guy, but I still get laid and I still get relationships by being sweet, not overly sweet or anything (such as being too needy or buying her stuff on the first date or second one for that matter) I am 6'4, thin, and handsome by the way :)
