Hello, I am 13 and I just started puberty and my penis is 2 and 1/4 inches long when in a boner. I was wondering what is the average size for a penis before puberty

Hi Glenerd,
There isn't an average. Even at 13 it's all over the place as some guys haven't started puberty and some have almost an adult sized penis.
Before puberty you really don't have many erections either.
For a 14 year old the average is about 3-4". For a 15 year old 4-5". Average for an adult is 5.1".
