I tend to find Caucasian guys with dark brown-blackish hair the most attractive physically. Though multiracial (is that a real word? o_o) guys can look pretty attractive, too. It's appealing in a really exotic way. ^_^

Being attracted to a specific race, or the way a person looks, isn't racist. I used to have a friend who found Asian girls more attractive than any other females, and he'd always beat himself up about how racist he thought he was. I always thought it was kind of silly - it's no more racist than having a preference for brunettes over blondes, or anything like that. It's physical attractiveness. It's not like judging someone's personality, intelligence, or talents. But I guess it just depends on how you define racism. *ends the rambling*
