Alright, so I am worrying about when I will pass puberty. I will give you a few details about me. My penis is 4.7 inches erect, I am 5"4, I weigh 120 lbs, I have curly pubic hair ( a lot), I have barely noticeable armpit hair, it's just started growing black, I have little facial hair, I masterbate a lot, and my voice is CONSTANTLY cracking, ( It cracks like almost every minute. When will my voice change? When will my penis grow? I am really worried about this..
