im 16 years old and it seems that i am harier then all my friends, im the only one with hair on my chest, and hair on the rest of my body. can masterbation cause hair to grow more/faster on the male body. i dont masterbate everyday and ive been doing it for about 3 years. im thinking it may be my background (italian) but im not sure. so is it caused by masterbation or is it just hereditary?
