Because of the penis factor.That's all.Don't look any further.
That's a myth.
Studies have shown that white Europeans and black Africans on average have an erect penis of equal size, while Asians considerably smaller. The impression is because in black guys it does not shrink as much. That's all.
It's just a myth.
To me the hype about black guys is only to do with music and MTV. It all started with Michael Jackson back in the 80s and they should thank guy for it.
Of course Africans have absolutely nothing to do with US black mucic culture such as rap, but just try to exploit the situation. There are many girls brainwashed by MTV, so all that blshite on TV will surely get your laid.
Though I have black friends and I'm white myself, I don't like reverse racism, that is when some guys think in fact that they are better cause of their skin color.
And that seems just to be the case for you 'superman'.
