Hello, I'm 16 and going on 17 in a few months, i was just wondering why isn't my penis growing... Its been the same size since i was like 10. My ball bag has dropped, i have a deep voice, I'm getting a little facial hair and i have armpit hair, but no growth. The last time I had sex was about 2 years ago and the girl told me I had a small penis and i was really embarrassed. My penis size is 2 1/2 and on hard its 5inches. please contact me asap :)
