I've been around many black guys in sports (college football) and the service, many of whom had big cocks. I don't recall any of them outright bragging about the fact.
(Well, hardly ever!) So kinda wondering if you have had any experiences along this line?
I have heard a few "humorous" or "joking" responses from black guys somewhat like the one in the previous post. Frankly, most the talk I've heard about black guys having big cocks is from whites guys.
On the aspect of interracial sex, I did hear occasional muttering from some of the white guys in football and the service about black guys hitting on white girls. "Why can't they date women of their own race?" It was a real sore spot with some.
Of course, I mainly saw this all from the white guys' perspective. I suspect blacks may have talked about it a lot differently among themselves. I remember reading the results of a sex survey where the question was asked if black guys had bigger cocks than whites. Most of the white guys said "no" and most of the black guys, "yes".
