Beautiful dick, by the way!!!!
The reason people talk about "Big Black Dick" is that I'd say your chances as a "size queen" or "bottom slut" of getting a "BBD" is a lot higher with a black male than a white male. I'd say 50% of black men are 8" or larger (longer), while only about 30% of white men are around that size. Although, you might actually have more white guys in that 7-7.5" range, because I've noticed either a black guy HAS IT or else they're only about 6-6.5". I haven't encountered many black men in that 7-7.5" area.
