What does it mean if you act your opposite race?

I mean, I'm black. But I seem to act white. I listen to white music. I'm not interested in the hip hop and rap. I crush on white guys. Never on black guys. My cousins are always teasing me. They call me "white girl". It's not like I'm ashamed of my race. I'm proud to be black. But it's weird that I act white. Does anyone know what's up? Mental thing? Sub conchince? ANYTHING??
