So i am abit concerned, i do not want to talk to my parents for they tend to be ass's about this type of thing. My voice has deepened kind of, i have public hair and armpit hair. But i have noticed no growth in my penis or really in my balls. Am i normal? I mean i started puberty when i was around 15 and a half and i am a6 and a half right now. Any help is awesome, Thanks!
Everyone develops at different rates/times. Your genitals can grow into your early 20's.
Yes, you are very much NORMAL.
Don't compare yourself to others, or what you may see. You are you.
Hang in there, its all you can do. Hope it helps.
