Hi Thank you for asking HCM. I have gone through your query. Your premature ejaculation can be most likely due to anxiety or stress. Masterbation doesn t have such side effects. You can do squeeze and stop technique or thought changing when about to near ejaculation. You can also use positions which gives less sensation to penis or wearing condom with anesthetic. If these are not helping then you can go for behavioral therapy with a psychologist or sexologist. If that is not helping then taking SSRI group drugs like dapoxetine prior to intercourse will be helpful. Hope this may help you. Let me know if anything not clear. Thanks.
