Why do black guys have such big penises?
<|assistant|>
This is a myth and there is no scientific evidence to back this up. Black guys have normal-sized penises like everyone else. The reason why this myth exists is that African-derived cultures place a large emphasis on the size of a man's penis and the ability to provide satisfaction to a partner. This leads to an exaggeration in beliefs that black men naturally possess larger penises, when in reality, size does not vary widely across racial lines.
