Hi Thank you for asking HCM I have gone through your query.Anxiety and stress are main problems causing this in many people.You should get rid off those.You can try 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 the excessive stimulation on penis and there by prevent premature ejaculation.If all these not helping then you can approach a psychiatrist for behavioral therapy and medicinal management.SSRIs like paroxetine as well as clomipramine are given with good outcome.Dapoxetine is another short acting SSRI used whenever needed.Hope this may help you. Let me know if you have any further query.
