Hi Thank you for asking HCM I have gone through your query. Usually thought changing when about to get ejaculation, changing to position which gives less stimulation on penis , condom with anesthetic and squeezing technique works in so many people. But if that is not helping then behavioral therapy with psychologist will be helpful. If that is also not helping then SSRIs like dapoxetine or phosphodiesterase inhibitors like taldalafil will be helpful. Hope this may help you. Let me know if anything not clear. Thanks.
