Premature ejaculation occurs when a man ejaculates sooner during sexual intercourse than he or his partner would like. Premature ejaculation is a common sexual complaint. Estimates vary, but as many as 1 out of 3 men say they experience this problem at some time. As long as it happens infrequently, it's not cause for concern.
However, you may meet the diagnostic criteria for premature ejaculation if you:

• Always or nearly always ejaculate within one minute of penetration
• Are unable to delay ejaculation during intercourse all or nearly all of the time
• Afraid of foreplay as it may cause ejaculation
• Feel distressed and frustrated, and tend to avoid sexual intimacy as a result

Both psychological and biological factors can play a role in premature ejaculation. Although many men feel embarrassed to talk about it, premature ejaculation is a common and treatable condition. Medications, counseling and sexual techniques that delay ejaculation — or a combination of these — can help improve sex for you and your partner.
