i am 11 and my voice is somewhat deep. my genital area has a lot of hair, about 6-7cm tall, but no hair on my testicles. i don't have any hair in my armpits, but around my nipples and on my belly, there are hair that is about 3mm tall. my penis is about 4inches erect, and 2 inches flaccid. i have had only about 3 wet dreams, but i have some erections. question: am i in the middle, start or end of puberty? and how long would my penis be at the end of puberty, at this rate?
