Hi, welcome to HCM. Thanks for asking your query at this forum. We understand your concern. I have read your question carefully and understood it. I will try my best to answer it. I can understand your suffering. At this young age, it happens most probably due to wrong beliefs and anxiety related to this belief. Let me explain you in detail. In our society most of us think that masturbation causes physical and sexual weakness, so our unconscious mind does not permits us for this act. But desire for sex is a basic instinct and due to sexual urge often we indulge in this act. After doing the act the person feels himself guilty and decides to abstain from the act, but does again due to intense sexual urge. This continues for years and later on the person develops fear of having some sexual or physical weakness. This fear causes anxiety which may lead to sexual dysfunctions (like erectile dysfunction and premature ejaculation) and feeling of bodily weakness. In fact masturbation is safe sex practice and it does not cause any kind of sexual or physical weakness. I suggest you to relax, avoid thinking about effects of masturbation, have balanced nutritious diet, regular exercise, some time for recreation and socialization, adequate rest and enough sleep. This will relieve you anxiety and worries. If needed you may be prescribed few medicines/psychotherapy for a period to relieve anxiety and sexual problems. I hope it answers your query. I wish you all the best.
