There is a famous legend that black men have bigger penises than caucasian men.
This actually started in the last century when slavery was rife, and black people were considered an inferior species. In order to perpetuate the notion that black people were little better than animals, white racists would claim that black men had large penises which added to their animal characteristcis and behaviour.
In our more civilised society, the notion that black men are animalistic has gone, but the penis size myth lives on - and no doubt black men do little to disprove it.
