I am 20 yr old , I have been Masturbating since the last 10 years , I wasn't aware of the effects but now that I'm about to be 20 in upcoming month I feel tensed as I have noticed that my penis is shrinkage and there is low libido, premature ejaculation, please can you tell me if I stop right now and exercise, will i recover and reverse the damage naturally? Will the penis come back to its original size? I'm very tensed doctor, please tell me,I can't tell to my parents too, will i recover and be normal in 5 years ? If i totally stop masturbation?
