I think it's much easier to be friends with girls you're not attracted to, but that's just me. Otherwise, there's the tension and the inevitable hurt feelings when the guy tries to cross the "friends barrier" and it just doesn't work. Well, I guess that's my experience at least.
And girls in bands might get cut a little slack, as in, if a girl can kick out the fuckin' jams and is attractive, it WILL make her more attractive. But Donna F. is and always will be fugly no matter what. Ya can't polish a turd.
