Okay I'm 21 years old about 6'0-6'1 around 120 something lbs. I feel like i got everything in puberty ( voice got deeper, hair all over you know etc) except penis growth. Idk if it's because i'm skinny or what. Do I need to out on some more weight and muscle for it to grow ( I don't workout a lot but i'm active )or do I need to go see a doctor.I get erections so I know it works. It just hasn't grown to its adult size and this is mainly the reason i'm still a virgin. Maybe this is just my size and i'll have to just deal with it. any advice will help, i'm all hears and if you need any information about me to help that'll work too.
