Hi, I was worrying about my penis size and I don't know if it's too small or big, I'm 13 and I don't think I've hit puberty because I have no spots, armpit hair, or pubes my penis size is nearly 3.5 inches when erect but idk if that is as big as it gets is this normal

Hi Anonymous,
3-4" is average, erect for a 13 year old. Average for an adult is 5.1".
It'll grow.
