If it concerns you try taking control of your like. Decide on a time that you will allow yourself to masturbate, only the hour before sleep, only during your shower. However it fits most comfortably into your day. When you feel the urge to masturbate at other times remind yourself that you'll be taking care of that need during the normal time of day.

You need to take control soon. It only gets worse. I'm 24 and I started at the age of 12. I now masturbate around 16 times a day. I can't stop. I spend a lot of time watching porn as well. I will rub one out. Do some homework then rub another. I'm not even having and orgasm anymore. I think something is wrong. Anyways I suggest that you get some help if you don't want it to take over. You know better than anyone if you over reacting.
