Seems to make sense that most photos we see here will be a least average if not bigger. Not many guys want to show their units in the first place, even fewer would if it's below average.
In a similar vein, I haven't gone without a shirt in public (not even my own yard) in years. I have a big belly and I know it's not pretty to see. Most shirtless guys I see have decent bodies. Sort of a parallel with penis size. You show off what you have that's worth showing, you hide what you don't want others to see.
When I had a break from the Gym for a few months, it started to occur to me that it is indeed quite strange that I have posted photos of my erect penis on the internet. Not that I'm one of the big ones, and I'm not taking them down. Just saying I understand better now why a lot of guys don't.
