First thing.
MASTURBATION DOES NOT CAUSE ANY HARM TO THE BODY OR YOUR PENIS OR SEXUAL ORGANS. NOR DOES IT HAVE ANY EFFECT ON YOUR MIND OR BRAIN.
Hence, remove this notion out of your mind that masturbation is harming u.
Second, it's absolutely normal to masturbate. Just like u go and pee when u feel the urge, u use the toilet when I wanna pass Stool, the same way, humans have to remove their semen when they have the sexual urge. It's possible by regular sexual inter course or masturbation. Since daily sexual inter course is not a feasible option for most of the unmarried guys in our country. The solution is that u should masturbate regularly.
Next Steps
Trust me. And keep masturbating on a regular basis
