how long does it take for a guys penis to be full grown? im 13 1/2

From the start of puberty to the end of puberty.
So that is about...12 to 20 or so...varies person to person :D
Thats a very general age but its an answer :P

For everyone its different-
Puberty can range from like 11-20
the penis gets bigger near the end, because pubic hair is grown before it.

[itsallaboutme]

usually puberty ends when you're 19, 20...so by then you'll have a full grown penis.

[Stevo 69]

It will stop growing once you've ended puberty

Depends, I'd say.

I wish I knew the answer to that question because I'm 15 myself and don't even have all my pubic hair yet
