[|AI|]  Thanks for writing to Chat Doctor. I have gone through your question and understand your concerns. Masturbation in private or with a partner is a normal and healthy part of sexual enjoyment. There is no such thing as excessive masturbation or a lot of masturbation. Weakness is due to anxiety about perceived excessive masturbation and its effects. Don't worry. Masturbation itself is harmless and itself does not cause weakness. Your ejaculation occurs soon with little excitement. You can gain ejaculatory control over a period of time by practicing following methods.1. Stop-start technique of behavior therapy.2. Medicines like Fluoxetine 20 mg day or Paroxetine CR 25 mg per day. (To be taken under medical supervision only)3. Pelvic muscle strengthening exercise. (Keels exercise). You can read on internet.4. Penile squeeze technique applied at the point of ejaculatory inevitability.5.  Applying a local anesthetic ointment to glans penis prior to masturbation. Practice above behavior method regularly. This will help you. Wish you good health.
