I'm white and I've dated mostly white and hispanic. I spent a decent amount of time with a half-Cherokee girl who really had so many Cherokee features (not your stereotypical ones, the ones you expect when you've been around anyone with Cherokee blood!) but for the most part, I haven't dated any other races. Not that I wouldn't have if I met the right person.
I don't tend to find myself very attracted to African Americans, despite the fact that my recent girlfriend is a lighter skinned black gal who is one of the most gorgeous women I've met. There are a few who I could see myself with, but there just aren't those yes-I'm-shallow features there that I am attracted to for the most part.
