i must admit i do have a bit of a weakness for black guys. and it could possibly have to do with the opposite skin, etc. since i have blonde hair/blue eyes and all that.
i've never dated one, but i did hook up with one once. i don't find that i find MORE black guys attractive, but i find that when i see a good looking black guy I am very much attracted to him. i do find it harder to find a really goood looking black guy, than a good white guy.
