I have a puberty question
I am 16 now and am a junior in high school and have yet to see much going on down there. i have some hair that has darkened and is curling slightly but my penis hasnt grown much at all. When erect it is about 3.5 to 4 inches. i also have a high voice, never get pimples, have no armpit hair or much other kind of hair on my body besides my head hair. Also when i masturbate i only ejaculate a tiny amount. Should i worry? everyone else is much further in puberty than myself.
