mark spring answered question 11/29/2010 I'm 16, Balls havent dropped. No armpit hair. Very few long black hairs above penis... My penis is only about 1 1/2 - 2 inches long... About hand size when erect... Can someone tell me main sign of the start of puberty and how long till my penis grows? You are probably just a late developer. Don't worry. Everything will be fine. If your'e worried see your doctor.
