About 6". Also measured in college/high school days, compared with a few friends. I was in the middle. I'm guessing, not really scientifically, that average is around 6". Obviously the range is wide. Prediction: Replies here could play out to give the illusion that average is a bit larger than that, because there will be more respondents with a larger size than average, than the opposite, I'm guessin'. Plus I'm thinkin' there might be a larger-than-average dick size to this whole establishment.
