Well,
I must admit, I am with Carl on this one (GASP!).
It's another one of those guy things I think . . .
We men are more surface-oriented. Women will more often look below the surface and be attracted to attributes other than looks (I am speaking when they don't really know the person, but know about them). Of course they usually THINK they know the person, and why they are attracted . . . witness that cheerleader and the quarterback. I could give lots of real life examples too.
Most men initially have a "one-track" mind mindset.
I don't think there is one UGLY female celebrity that looks like a heroin addict that I would be attracted to in any way. You won't see many guys chasing after the likes of Janet Reno either . . .
(tried to think of an example similar to Steven Tyler, but all I could come up with is Janet Reno)
