How To Get Rid Of Nightfall?

Good evening sir, actually i started masturbation at a very early age, as my cousins directed me to do so. Though I'm good at studies but now i'm feeling that because of excessive masturbation i'm loosing my memorising power which is hampering my studies. AT present i'm doing MBA, THOUGH i have stopped masturbating now but nightfall often occur even now and then. There was another problem that my testis and Penis have tilted to one side due to excessive masturbation in early years and it had also become thicker from middle. Plz give me necessary guidance and does it hamper my sexual power with my wife in future.
