I wanna end this f*cking vice once and for all and change my life radically forever

Well, what's up everybody I'm Ryner 20 years old and for a long time I have this terrible vice, since I was a adolescent something that has affected me a lot I'm quite aware of this problem think it's the first step to being able to change situation difficult of our mistakes, see, assume the consequences to beginning a new life. Like anyone I've tried to quit many times, but I couldn't get it but I'm willing to try one more time, I will never give up until I achieve what proposed me
this time I want to do it through sport I feel motivated and at the same time the desire to masturbate diminish it but struggled with that every day, I've been training in the gym for since some time masturbation along with the sleep disorders that has created me don't allow me to achieve adequate muscle growth so it's more than necessary to end this at once!
