Hi Thank you for asking HCM I have gone through your query.Avoid stress and anxiety.You can stimulate your partner to higher extent before getting yourself stimulated.You can also try squeeze and stop technique when about to near ejaculation.Deviating your thought to some thing non sexual when nearing ejaculation also helps.You can put on a condom or apply anesthetic gel on penis or put on condom with anesthetic helps to decrease the oversensitization of penis and there by premature ejaculation.If all these not helping then approach an Urologist or Sex therapist or Psychiatrist for behavioral therapy and medicinal treatment. Hope this may help you. Let me know if you have any further query.
