What is happening in puberty to a boy?

Answer 1

Visible signs of puberty... growth of hair on your scrotum and in the region of your penis (also around your anus), growth of hair on your ankles and in your armpits. Growth of facial hair. Your penis will get longer and thicker, your scrotum will get darker in colour and hang lower to accomodate the increasing size of your testes. You will sweat more and your sweat will begin to smell. You may get spots and blackheads. You will grow taller and your muscles will develop. You will find yourself think about sex a lot and you will get erections. You may find yourself mentally comparing the size of your own penis with the penises of other boys in the showers at school, this doesn't necessarily mean that you are gay, just that you are curious which is perfectly normal. You may also feel the urge to masturbate and when you do at some point you will eventually produce sperm. Oh and your voice will "break" and lower in pitch as your larynx (voice box or Adam's apple) enlarges.

Answer 2

your balls pull away from your body ( A.K.A your balls drop ), you experience serious growth EVERYWHERE, pubic hair starts to grow. As well as armpit, leg, and foot hair. When cold your balls pull to your body to keep warm, and when warm they drop to the scrotum (or ball sack) to cool off.
