some guys, especially showers, are very big at least when flaccid. whether you see it through shorts or naked, at what size (length x girth) does it really catch your attention and evoke those 'ohhs and ahhs' in your mind. i'm about 4 x 4 flaccid and i think that is pretty average. you can speak from experience of people being impressed by your own cock or you yourself seeing one that caught your eye
