PME is one of the common psychosexual problem. There is usually a performance anxiety associated with this problem. In an average the intravaginal ejaculation time is 3 to 7 minuets. For PME try to be relaxed during intercourse. Never do sex in hurry. Do slow penetration and follow start and stop technique. It will increase your self control. You can practice start stop technique even during masturbation. Medicines are there but can’t be given without proper assessment of general physical status. Avoid any kind of substances. Thanks
