Addiction of masturbation. And how?

Hello doctors, i am 21 now and have been masturbating once or more times in a day for last 8/9 years almost. As per the side effects available on internet, i am also suffering from some of them like premature ejaculation, fatigue and tiredness, curvature of the penis, lack of concentration, low sperm count and insomnia. I have fighting with it since I decided to cut down or quit on it and i am on my way to achieve it. But the points which i am worried about are as follow:- 1. Is there any test available to know more about sexual problems, or their recovery methods. 2. Diet, foods, methods and medicines(if needed) to recovery of premature ejaculation, low sperm count and other sexual problems. 3. Possibilities to get curved penis straight and how? And would like to have more advices of expertise about my journey of recovery. Thank you.
