I know someone that tops all those guys with the smallest cock... Mark Last. He only works as talent in his own stuff but he's got an itty bitty tinnie winnie peenie. He even uses a cock ring to help him get hard, when he masturbates he lays on his back with his legs in the air annnnnnnnd he eve has this long black piece of cloth that wraps around his waist all around both his thighs and balls to trap blood in his dick. Its pretty sad and looks pathetic on screen. He makes himself cum when he's soft. It's very bizarre. I've witnessed this by being with girls who've shot with him.... sweet guy, but can't do it well on screen.
