I just turned 15 about a month and a half ago. Im 6'1 and have hair on my groin and pits. My penis is 4.7 when hard but it hasn't grown since I can remember is this normal
Yes that is normal. The penis usually grows earlier on in puberty but can still grow until your late teens or even early 20s
It MAY grow more, but it also may not. There's nothing you can do about anyway, so just enjoy what you've got. :)
Does vitamins help your penis grow?
