I'm half black and I have hardly ever found black women attractive. Even though I lived and went to school in a primarily black area, I met very few black women that I would "attractive" (obviously subjective) and would be at the bottom of my list for sure.
That doesn't mean I haven't seen some beautiful black women, but I haven't found nearly as many as I have from other cultures. Additionally, many black women completely let themselves go here in the south by their mid 20's, becoming morbidly obese while being pretentious enough to start every day with "I am fine! Damn I look good!" No.. No you don't..
