Lol. I don't remember the exact term for the statistical bias that results in the release of mostly only data that tend to be on the ideal side, but I'm pretty sure that is in operation here. Men who are proud of their bigger "data" and evidence for them are more likely to release/show them off or, at the very least, "not care" if they get leaked for obvious reasons. If not, people who have personally seen and touched them will tend to brag about them to others as well. Hence, the rumors about so and so (not just celebrities) having a big (and small also) dick are usually true. Because no one cares to report the unremarkable to others. But believe you me, the reason there are no such dick rumors, data and pics/videos of the penises of the vast majority of men -- regular ones and celebs alike -- floating around despite the ubiquity of self-taken dick pics is that most of them fall within the mean/median length range of 5 to 6 inches when fully erect, per the scientific studies.
