Am I racist against my own?

I am a black female who has always been around blacks, but went to schools that were predominately white. I seem to have a preference for white guys when it comes to attraction and if I envision myself being married, it is usually with a white guy. It feels "weird" with any other race. I thought I wasn't like this, b/c I have found black guys attratice. One black guy I would like to date (but he is too old for me). He is a chemist, really nice, smart, funny, and well dressed. I am attracted to guys like that I suppose. What is wrong with me?
