premature ejaculation

Premature ejaculation (PE) is a male sexual dysfunction that occurs when a male expels semen (and most likely experiences orgasm) soon after beginning sexual activity, and with minimal penile stimulation. It has also been called early ejaculation, rapid ejaculation, rapid climax, premature climax and (historically) ejaculatio praecox. 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 (ICD-10) 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. In males, typical ejaculatory latency is approximately 4–8 minutes. The opposite condition is delayed ejaculation.
Men with PE often report emotional and relationship distress, and some avoid pursuing sexual relationships because of PE-related embarrassment. Compared with males, females consider PE less of a problem, but several studies show that the condition also causes female partners distress.
