my name is john and i am 16 years and 4 months old. I have pubic hair, but it is not alot and it is growing very slowly.My skin has been oily and i have started getting pimples for a year now, and over the past 5 months, my voice has deepened, but i have not noticed any change in the size of my penis area. I have been starting to grow a little bit of armpit hair. i feel like puberty has cheated me, and i am very embarresed and am to scared to see a doctor about it. help?
