Of course they do. I'm going to show you a picture comparing Criss Strokes to Mandingo. It's the same porn star who is fucking them. Both guys have the same size cock! It's all perception that black guys have bigger dicks.

Aside from the placebo effect of women expecting it, they have a few more things going for the visual effect: 1, they seem to be thin from the side view because the bottom compartment of the penis isn't as big as more white guys tend to have. 2, simply the skin color can change perceived size. The same goes for how much muscle it looks like someone has. Darker skin produces a visual effect different from white skin. 3. I think black people have looser tendons down there. It's the same effect as that penis surgery that makes the penis hang an inch longer downward but actually does not contribute at all to it's fully erect length, so it doesn't affect penetration ability. White guys, people who evolved in colder locations, have more of a protecting mechanism to keep the cock tucked inside until it's time to fuck.
