Another question here, When does the penis generally stop growing? Like how old are you when your penis is done growing? Thanks
The penis can grow into the early 20's but I think someone said average is 18 and 19, but it varies with everyone, like size...
Each person is different and grows at different rates. It's difficult to tell what the average age is.
The average seems to be more like 16, but it varies a great deal.
