For Black men, sex is a major part of our dynamic energy. It's as well what white women/men often see when they look at us. When you watch Usain Bolt doing his magic on the track and field events, you don't imagine him as being a humble banker when out of his jersey, but instead try to imagine how excellent and raw he must be in bed. That raw energy you see in is does get distilled whenever we're having sex, and that's what attracts white women/men toward Black men. So roughness has little to do with it; it's just the way we're built.
