Hi Thank you for asking HCM I have gone through your query.You should get rid off anxiety including performance anxiety and stress as those are major offenders in premature ejaculation.You can practice squeeze and stop technique.You can stimulate your partner to maximum before getting yourself stimulated.You can deviate your thought to something nonsexual when you about to near ejaculation.You can put on a condom or condom with anesthetic which will decrease excessive stimulation on penis and there by prevent premature ejaculation.If can also try different position which gives you more time.If all these not helping then you can approach an urologist or sex therapist or Psychiatrist for behavioral therapy and medicinal management like antidepressants. SSRIs like Paroxetine or Dapoxetine is the usually prescribed drugs for this.Hope this may help you. Let me know if you have any further query.
