Reading this just lead me to the answer about this entire topic of black men getting black women vs white women... CULTURE
Black women expect certain things from black men, that ONLY come from black culture. Non-black women do not factor these things in at all. If they do, they only base it on you having culture, and not a range of how good it is.
A black woman will want you to be able to pull off our swag. Our way of speaking, dressing, dancing, walking, joking, etc etc.. All of it. Our culture says what a nice haircut looks like. The avg non white woman doesn't know an uptown fade from a regular ceasar. A black woman can hear you talk one way at work and another with your boys and not think twice. A non black woman is madly in love with the way you talk with your boys and laughs at brothers that talk "too white". Those brothers don't have any of the culture according to them. "oh you can't even dance" But a black woman will not only want to know if you can dance, but do you know the electric slide... There's also that intriguing factor to them being welcomed into our culture. We don't really yearn to be welcomed into non white cultures and take up their way of doing things. If we go put on a suit and tie, we put a little extra flavor on there. If they try and dress "hip" it's always a carbon copy. We ain't really looking for their style like they take from ours.
These are all generalizations but you see the point. That's why it's typical easier to get non black women. They already excited you black. A black woman is not. You got to stand out now above the other black men in some other ways. Now of course that doesn't mean ANY brother is going to get snatch the finest non black women. But it's a lot easier to step up a level or two when your culture spots you two points off rip.
