Premature ejaculation is diagnosed based on typical symptoms. To understand your problem, your doctor will need to discuss your sexual history with you. Be frank and open. The more your doctor knows, the better he or she can help you.
If your sexual history fails to reveal significant mental or emotional factors that may contribute to premature ejaculation, your doctor may want to examine you. Your doctor may examine your prostate or do neurological tests (tests of your nervous system) to determine if there is a physical problem that could be causing premature ejaculation.
