im 15 im small, im pretty sure my voice has broke ive got hair everywhere except my armpits. my penis and testicles havent grown im about 5 inches erect. my foreskin has alresdy broke but i done that
Sounds NORMAL to me.
The average for an adult male is 5.1" erect. At 5, you're almost there.
Armpit hair OFTEN comes in later, 16 or so is NOT unusual.
Your penis can still grow into your early 20's.
Hope it helps.
