Hi Thank you for asking HCM I have gone through your query.The first thing you should do is avoid anxiety and stress.Even performance anxiety in sex also can cause premature ejaculation in some.You can try following methods:You can do squeeze and stop technique.You can stimulate your partner before getting yourself stimulated.You can deviate your thought to something nonsexual before getting yourself stimulated.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 medications like SSRIs such as Dapoxetine or clomipramine.Hope this may help you. Let me know if you have any further query.
