Firstly, for your age, you are well down the jack-off league. Most boys your age are doing it 3 or 4 times a day.
However often you do it, it won’t make any difference to the size of your penis, any more than walking a lot would give you big feet.
Masturbating is moving the skin outside the penis up and down the shaft to also stimulate the nerve endings in the glans (head). The muscle or blood vessels inside the penis develop as part of your family genetics and DNA.
yes TONY is right it depends on how often u do it and how hard u do it to. and belive me i am a very hevy set dude i want my penus bigger then the next guy lol but u you are all set for life on that part
