I've seen a lot of white men/black women porn. It's not as common as black men/white women, but there's a ton out there.

I can't recall ever seeing porn with a white man and a black woman, actually, unless they were all in a group.

Ha! This was my first reaction as well. I see way more black man/white woman sort of "taboo" porn than I do the other way around.

Hrm. I see far more black men on white women porn than I do white men on black women porn. Actually, the latter is quite hard to find whether it be in an adult store or online.
