Is it normal that i love black girls this much??

I don't dislike other types, but I had a relationship with a black girl about a year ago, and have had dated other black girls, but from there on I think they are beautiful, not the getto ones the half something half black, the way they look, the color of their skin, the way they kiss, when I go out with someone else that is not black I feel like am missing something, and am trying to be really into it but I just can't, but when I go out with a black girl I go crazy, not for sex really, but for the feelings i don't feel the same thing with other girls, I guess it's true when you go black you never go back haha! Am Mexican by the way and am getting obsessed with black girls, is it normal? those any one else feel the same way or or close to it? Thanks for reading my story...
