Hi, thank you for using health care magic. I can understand your concern. There is technique called start -stop technique , and squeeze technique which can offer you more control over ejaculation. Medicine like sertraline , escitalopram are useful in reducing premature ejaculation , this medicines are usally prescribed by psychiatrist for treatment of depression but for your condition they are also useful. So i would suggest you to consult psychiatrist for further help if needed. Psychiatrist can also help you out through behavioral therapy in your condition. Hope this will help you. Regards.
