Hi Thank you for asking HCM I have gone through your query.First thing to do for premature ejaculation is avoid anxiety.Involve in foreplay with your wife and stimulate her to high extent before getting yourself stimulated.You can think about something non sexual just before you start getting the feel of ejaculation and continue when that goes.You can also practice squeezing technique when feel of ejaculation.You can use a condom which decreases sensitivity on penis and premature ejaculation.If that is not helping then you can use anesthetic to apply on penis or condom with anesthetic which prolongs ejaculation time.If all these not helping then approach a urologist or sex therapist or psychiatrist for behavioral therapy and medication.Hope this may help you Let me know if you have any further query.
