I just turned 15 around a month ago and i'm around 5ish inches when I measure my penis with the fat pushed down. I'm 248 lbs and my friends keep telling me they have a 7-inch penis when mines 5:l. Is mine normal? and what is the average weight and penis size for a guy like me. I'm 6ft tall and can produce sperm {white sperm} and growing a moustache and i have some armpit hair with a bush of pubes. and is there anyway to increase my penis size or effect the growth of it during puberty. Thanks a ton if you answer.
