Hi I'm 14 years old and I was wondering well first I have a 3 inch penis unerect and a 5'8 inch penis erect... and I was wondering will my penis still grow or is it done. And a little info I still haven't went through a growth spirt and I'm 5'8 or 5'9 feet tall idk if that has to do with anything with penis size but yah. Could I still be growing or am I done?
5.1" is average for an adult. Chances are you are NOT done growing yet though. Average for a 14 year old is about 4".
Your penis can grow into your early 20's. You'll likely also continue to grow taller until 18 or so.
It varies as we are all different but I think you're still growing.
