text: this is so sad that it cant be answered...? i was answering a question when this question popped up..... "some kid" asked it. "is 3.5 inches ok for a 13 year old? going through puberty?  i am 13 years old turning 14 in two months and i have been going through puberty for almost a year now. i still see more changes in hair/height/etc. well i just wanted to know if 3.5 inches when erect is good enough for a 13 year old, and when will my penis probably stop growing?   also what is girth and how do i find it out lol?  and if you have been through puberty it would be helpful if you could tell me what your size was at what age, and when did u stop growing thanks.  also i wanted to know if masturbation makes the penis grow more?? or does it slows down the growth"  isnt that sad? i think it is sad that your picking on a 13 year old. if his question was too sad to answer, then why did you answer it? find something better to do.
