Why is it 10 years ago i never would have looked at a black woman but now i find myself lusting after them?

Its been quite a change in and i don't know where it started, needless to say i think i was more racist back then, now i don't think i deny myself my feelings as much, i m just saying this is somewhat of a large step for me and i wonder what triggered it and why i have given in as it were, i feel more liberated in this sense, i can say the same of most races of women, though i seem to like the way black women look better than the other races, i still like my white women the most and see myself still marrying a white woman, just wondered what you might think of this.
