I am 16 and my penis hasn't grown? I have hair every where and can cum but my penis hasn't grown should I be worried or wait it out?

Hi Guest,
How big is your penis?
Lots of guys say it hasn't grown but you don't often see a 3, 4, 5, or bigger penis on a newborn.
Your penis can grow into your early 20's. A recently released study indicates that the average size of the male penis is 5.1".
Hope it helps.
