bigness of penis
Lorenzo von Matterhon was diagnosed with Phallumegaly at a young age. He grew up without learning how to ride bike, without being able to play little league (protective cups are too small) without being able to feel comfortable in a locker room or a regular pair of shorts. And it looks as though he'll never be able to enjoy those everyday pleasures.
