How is it treated?
In many cases premature ejaculation resolves on its own over time without the need for medical treatment. Practicing relaxation techniques or using distraction methods may help you delay ejaculation. For some men, stopping or cutting down on the use of alcohol, tobacco, or illegal drugs may improve their ability to control ejaculation.
Your doctor may recommend that you and your partner practice specific techniques to help delay ejaculation. These techniques may involve identifying and controlling the sensations that lead up to ejaculation and communicating to slow or stop stimulation. Other options include using a condom to reduce sensation to the penis or trying a different position (such as lying on your back) during intercourse. Counseling or behavioral therapy may help reduce anxiety related to premature ejaculation.
