Hi, i am 13 and i am wondering when my penis will increase in size. right now my penis is about 2 1/2 in. - 3 in. i have pubic hair and my voice is starting to get deeper. i am embarrassed that my penis hasn't grow and i really want it to especially because school is starting in about 2 and half weeks and it is embarrassing in the locker room. do you think my penis will grow before then?
i also started puberty in my late 12s
