Hello dear I understand your concern When male partner ejaculates early before the female partner reaches to orgasm called early ejaculation or premature ejaculation. It isn t diagnosed by the time of masturbation. According to DSM 5 diagnostic criteria: premature ejaculation is defined if there is ejaculation within one minute after entering tin to vagina. There is no maximum duration for ejaculation. It depends on mood, environment, age, body make up. If you are unmarried then it is difficult to tell about early/premature ejaculation. This time will increase when you enjoy sexual intercourse with your partner. Do not be panic and apprehension. If problem persists after marriage then it is easily treated by drugs like sildenafil and tetrafol plus Meanwhile Avoid stress, drink plenty of water, eat healthy diet with lots of fresh fruits and green leafy vegetables, do regular exercise like walking and running for 45-60 minutes in morning followed by yoga for 10-15 minutes. Hope this may help you Contact further if follow up needed Best regards Dr. Sagar
