Cool thing I learned this in human sexuality class in college, but the average age that the male p***s stops growing in length and endowment is the age of 19.5 years old, keep doing your penial excercises!
The p***s can also grow if you lose weight. Why? Because the fatty tissue on the pubic mound retracts when you lose weight, making the length of the shaft appear larger, because it's showing more.
Also, remember that some men grow when they become erect, while others show exactly how large they'll be while flaccid.
