Noticed there are more skinny adult males whom are hung and MOST bodybuilders are lacking there of. Maybe it's the distribution of testosterone all over the bodybuilder's body compared to that of the skinny male's penis and testicles? Maybe the skinny male just needs some years to naturally buff-up to the bodybuilder. I was skinny/average growing up and consider myself average-to-large in penis/testicle size for my BMI and race, but I had to workout more to get the muscle and veiny at a normal pace (not excessive). Also noticed is the males of African-descent (not native Africans living in the country) in America, C./S. America and UK tend to be the most-endowed. Is their testosterone level and distribution responsible? Lucky men! Tell me your growth experience or lack there of.
