Premature ejaculation (PE) occurs when a man experiences orgasm and expels semen soon after sexual activity and with minimal penile stimulation. It has also been called early ejaculation, rapid ejaculation, rapid climax, premature climax. There is no uniform cut-off defining “premature”, but a consensus of experts at the International Society for Sexual Medicine endorsed a definition of around one minute after penetration. The International Classification of Diseases applies a cut-off of 15 seconds from the beginning of sexual intercourse.
Although men with premature ejaculation describe feeling that they have less control over ejaculating, it is not clear if that is true, and many or most average men also report that they wish they could last longer. Men’s typical ejaculatory latency is approximately 4–8 minutes
