Hey, I am 15 years of age, and positive I am in puberty. I have hairs under my arms, pubic hair about 1 1/2 inches above my penis and some on my penis, and I also have pretty hairy legs. I am wondering when I will start to grow? I would really like to get taller sharpish, because all of my friends are leaving me now, as in, they are getting much taller and gaining more muscle. One of my friends is even 6 2 already and he s the same age as me! So please some one answer this, when will i start to grow? I am currently around 5 4 - 5 5 My mum is 5 6 or so and my dad is around 5 9 - 5 10 So ye, please some one answer this question!! :)
