I just read an article in a science-magazine (EOS-magazine) and they were explaining why black people always look like they are having bigger dicks then white men. Well eher is the explanation:
When soft, a black dick is less elastic then a white man his dick. Because of that, the soft dick of the black man hangs lower. A white man his dick can shrink because of his elastic ability. But when black people are getting an erection, the dick doesn't grow that much anymore. But when white people get an erection, they can go from small to big. So dicksizes are the same.
Now, I know that people would say that they see more large black dicks then white, but that is just because the media is saying that black people are bigger. So, we are all the same
