Sir I have masturbated continuously 5 years (11 years to 16 yr). Then I have masturbated two or thrice in a weak upto 19 yr. Then upto 20 years once or twice in a weak. Now I am 21 yr. Sir now I am facing many problems like pain joint, weakness in full body etc. Sir now I have not so much power in my fore arms and biceps, it seems like weaker than previous. And my overall physical stamina is very down. How can I gain my previous stamina sir? please plz.
