It seems to me that one of the reasons that so many men are concerned about their penis size is that, being straight, they don't have much to compare it to. For the average guy it is probably a rare occurence to see another man's erection in person as an adult. Even with the statistics broadly available, seeds of doubt will remain for many. On the other hand, even a moderately active gay man will have a number of "comparables." They will have an opportunity to see how they stack up against a broad sample. It would seem that, even if you are on the low end of the bell curve, it gives you a chance to deal with it and move on. No real mysteries. To a degree, it would also seem that porn probably makes this worse on the straight guy, since most of the organs are at least above average in size. In my case, my flaccid cock is about 6" x 5", or right around the average for most erections. Looking at this and imagining that it was all I had as an erection, it sure wouildn't seem like much. Opinions?
