I have see able hair around my penis (started last year) but my penis hasn't grown at all nor has my balls, I also have some hair on my armpit it's not so much but it's seeable , my balls go lower the sack and one hangs lower than the other tell me why? after a hot shower or in heat, my voice is high, I get erections randomly in school and when I get excited over anything, my dad is 6"3-4 my mum is 5"6. My friends at school are a lot bigger than me! I feel tormented and small. My birth date is in August and I will be 15. Its making me paranoid rhat i wont get very tall, Am I in puberty? Will i hit a growth spurt? Am I due to be tall? Am I do for a big or many small growth spurts will I hit one this summer?and what stage am In puberty? What should I be looking forward to next???
