On average, how much does a boys penis grow during puberty? -
My 13 year old boyfriend has a small penis (about 4 inches) and we plan to stay together for a long time, so I-m wondering how much it will grow over the course of a few years.
I hope you found your soul mate, thats great!
Hes only 13, give him time to grow he has another 7/8 years left of growing.
He will probably reach the average (6inches) but its determined by genetics so who knows, maybe he will be bigger or smaller than that.
