How big would an average sized 13 year old penis be?

well mine was like..6 inches back then..but i think average around there..its 5 inches long..not sure about girth though..but yeah it will grow..mine did..mines now 9 inches..so no worries.

~Masturbation will not make you big or small, has no effect.
You’re still a young man, there’s no way to know. All I know is you aren’t done growing. The average size for a man is 5.5-6 inches. Possibly 3-4 inches wide?
Why not focus on something worth focusing on? No matter what you do, you won’t change the size of your penis. A hobby perhaps?~

suppose to be 3 inches , but it different ,depending on weight, height (if your weight more than average = you got bigger ) , and there is an equation on this issue ( short got big tall got small ) and there is joke on this ( if you got a Mercedes you don,t need to have a big one

probably 4 x 3 or 5×3 at most

ill check for you if its too small
if u no what i mean
;D

i guess mine was abt 11 cm wen erected

when I was 13 mine was around 6 inches but now its 8 inches so im sure yours will grow to .
