I'm 14, 15 in August. My penis in erect is 5". I have loads of pubic hair. I have a little bit of armpit hair, which is brown/black. (I'm blonde headed.) Voice has deepened a little. I'm around 5'3"-5'4". I know that I've hit puberty. I want to know what stage, out of how many stages.
There are 5 stages.
It's hard to say how far along you are. The primary indicator in a male is testicle size. They use a tool called an "orchimeter" to determine how far along you are.
Your penis is in the stage 5 range.
