Actually, I'm referring to vagina size. I've read before that black womens' pelvic regions are shaped somewhat differently and that shape will allow for more penis. It seems that their butts takes on a contour that is indicative of the different pelvic shape and also since more penis can be taken the extra butt padding is a natural bedding provided by nature to counter the big penis. I've known a few guys that have had sex with both white and black women and each one of those guys told me black women can handle more penis and were more into pounding power sex. If I recall correctly each one of those guys said he was 7" and more and the black women could easily take everything they could dish out with no pain.

Here's a discussion at BET that might be of interest. BET Community Forum Size matters to almost all (though not all) of the women posting there. Go to another forum where it is almost all white women, such as IVillage, and many of the women don't put nearly as much emphasis on penis size.
