Say there are 3 guys. Guy number 1 is 2 inches soft but 7 inches erect. Guy number 2 is 6 inches soft but also 7 inches erect. Guy number 3 is 3.5 inches soft and also 7 inches erect. When they are hard they are all the same size, so does it really matter how big they are when they are soft? Erect size gives pleasure during penetration, but does soft size serve much purpose other than filling out underwear?
