Hair growth has nothing to do with masturbation. It does have to do with genes which predetermine many physical characteristics and in the scheme of things is nothing to be concerned about. However, at 16 if you have been masturbating for 3 years how well will you be able to relate to a real woman when you think it is time to find someone special?
Many men can not have a single one on one relationship with a woman and end up never really long term happy or even content. They act happy but are actually sad, miserable, lonely creatures. It's all about the choices....it's all about the love.
it's your ethnic background trust me
