I've wondered if one of the reasons women tend to like tall men is that they assume that a tall man also has a larger penis. On the other hand, my personal experience is that most women really do not get excited over a large penis. Given the stereotype (fed by the porn industry and others) about black men, I also wonder if women who prefer black men assume that those men have larger penises. If so, then you can imagine the frustration of a non-black non-tall guy who is well endowed - but has no way of showing this off in a socially acceptable way. In any case, nobody would believe me without seeing it, but no woman ( who is looking for such a thing) would see it without believing me. So it's a catch 22.
