Hello thanks for asking a follow up question First of all I would like to tell you that masturbation is a safe and healthy habit. It is not associated with any side effect and it doesn t result in any serious concern to health. It don t cause weakness. So the problems you are suffering are most likely not due to masturbation. You have complaints of early ejaculation for which I would advise you to try relaxation exercises. Most common reason for early ejaculation is anxiety associated with sexual intercourse. So to reduce anxiety I would advise you to try relaxation exercises, breathing exercises to reduce anxiety and this will reduce incidence of premature ejaculation. The symptoms like shivering, palpitations, weakness etc are occurring due to anxiety. I would advise you to visit a psychiatrist for treatment. Medicines of SSRI group like Paroxetine can be utilised in your case. The medicine will help in reducing the symptoms of anxiety and will also help in premature ejaculation. This will help you in better functioning. For symptomatic relief medicines like low dose benzodiazepines can be used. Consult a psychiatrist for prescription. Thanks, hope this helps you.
