When I was much younger all of my crushes were white women. It was a white "woman" (girl.. rather) who kissed me when we were both 5 and playing a game. Ever since then I've sort of lost my interest in white women after learning how many of them really are, and how many of them are only intrigued by the Mandingo fantasy.
I don't want to be a fetish to my woman. I want her to love me for me, and I don't see myself getting that from a white woman which is why I haven't dated one.
This doesn't, of course, mean that I don't find white women attractive. It's just a psychological barrier that stops me from dating them as a young black male.
