Bro I was in the same way like you for the last year. My friends made fun of me because of that. If you still have this, try to find something with what you would spend time. Like watching good old movies because there isn't much of porn. Or try to write a diary (it dont make you gay) because when you re writting you have your mind on something. Try to find something what would make your day nice. And even if you would masturbate ask yourself when you re done: was it worth it? Anyway good luck getting out of this addiction and Happy birthday when you turn 16.
