My penis is 2 inches flaccid 5 inches erect i have alot of pubic hair i have armpit hair alot im 13 and i am 5'10 is this normal oh im also growing a bit of a beard.
3-4" is average for a 13 y/o erect. 5.1" is average erect for an adult male.
You can still grow into your early 20's too.
Flaccid size varies considerably.
