Okay so I'm 15 M and I have pubic hair but no arm pit, facial, and chest hair, I have leg hair but it's thin, I've noticed that my balls are getting bigger but my penis isn't and I don't know if this bc im going to be a late bloomer or something but let me know if this anything. ( should probably say I jack off once a week)
Hi Guest,
Armpit hair often develops later in puberty, 16 or older. The same applies for chest hair. Some guys don't get chest hair until their 20's. Not all 15 year olds shave, it's more common around 17-18. It's all normal. Don't compare yourself to others.
I'm sure your penis has grown some. Average for a 15 year old is 4-5". Average for an adult male is 5.1".
Masturbation won't change anything.
Hope it helps.
