Dear John, Thank you for contacting Healthcaremagic. I have gone through your question and understand your concerns. Masturbation in private or with a partner is generally considered a normal and healthy part of sexual enjoyment. Let me tell you young friend that there is no such thing as excessive masturbation or lot of masturbation. Just as excess of sexual intercourse cannot lead to weakness or paralysis, so also excess of masturbation. Sexual intercourse is not BAD HABIT, so also the masturbation. Weakness in legs may be due to anxiety about perceived excessive masturbation and its effects. Don t worry. Masturbation itself is harmless and itself will not cause limb paralysis. You can consult your physician to get examined for limb weakness. He will definitely assist you to come out of this problem. Please feel free to ask if you have any doubts or follow up questions. Wish you good health.
