Hey I am 13 and I have a little amount of hair in my pubic hair but not alot. Also I masturbate every day. Will that sloe down my puberty. Also I have like no hair anywhere else and still have a high voice and not so strong. My penis is also pretty small. When will I get bigger and more hairer.
It's impossible to know for sure, but probably soon. It's a gradual process though.
And don't worry, masturbating won't slow it down.
