A) how do you know? B) is 8" the shorter end? Um, 5 is average!
1) His bulge has allways been huge
2) Now when he has baggy underwear it seems empty but i know it is just really hanging, i've seen my fair share of those who seem dickless when they are not wearing thight underwear but suprice, the thing was just hanging peacefully and camouflaged
3) His photos on his purple boxer briefs, when he is standing front camera hands paralel to his body,
extrapolating his thumb to his junk on direct comparison,
4) Taking my own thumb as the source of the posible size in comparison, taking into account that my hand is way smaller than his, since i'm 5'9
In the short end because i'm using myself, an averaget to small male as the reference and guessing his dick size would double from soft to hard.
