Im a 21 year old male. I had stopped growing taller at the age of 14 at an height of 5'6. I'm still 5'6 and not growing. What could be the reason that I stopped growing taller? I was known to be a taller boy till I was 14. Is it due to masturbation that I stopped growing tall. I remember when I was in 12, 13 or 14 years old, I used to masturbate 2-3 times a day or sometimes 4-5 times a day. Is there still hope of growing tall at 21.
