Hello thanks for asking from HCM First of all just to psycho-educate you I would like to tell you that in most of individuals ejaculation occurs with in 3-4 minutes of penetration. Intercourse after penetration for half hour doesn t usually occur and this can occur in delayed ejaculation or anorgasmia which could become a bigger problem. So try to accept that thing. You have premature ejaculation and want to delay ejaculation time. Best method to delay the time is to divert and distract yourself from intercourse after penetration. This results in significant improvement. Some exercises like Kegel s Exercise or Pelvic muscle strengthening exercise, Start stop technique etc help to delay the ejaculation time and are very helpful. Even after this ejaculation time doesn t improve then visit a psychiatrist for help. SSRIs especially Dapxetine have excellent roles in premature ejaculation. Take a proper prescription of the drug before using this. Thanks
