Other studies report PE prevalence ranging from 3 percent to 41 percent of men over 18, but the great majority estimate a prevalence of 20 to 30 percent—making PE a very common sex problem.There is a common misconception that younger men are more likely to develop premature ejaculation and that its frequency decreases with age. Prevalence studies have indicated, however, that rates of PE are constant across age groups. History
Male mammals ejaculate quickly during intercourse, prompting some biologists to speculate that rapid ejaculation had evolved into mens genetic makeup to increase their chances of passing their genes.Ejaculatory control issues have been documented for more than 1,500 years. The Kamasutra, the 4th century BCE Indian marriage handbook, declares: "Women love the man whose sexual energy lasts a long time, but they resent a man whose energy ends quickly because he stops before they reach a climax." Waldinger summarizes professional perspectives from early in the twentieth century.Sex researcher Alfred Kinsey did not consider rapid ejaculation a problem, but viewed it as a sign of "masculine vigor" that could not always be cured. The belief that it should be considered a disease rather than a normal variation, has also been disputed by some modern researchers. Psychoanalysis
Freudian theory postulated that rapid ejaculation was a symptom of underlying neurosis. It stated that the man has unconscious hostility toward women, so he ejaculates rapidly, which satisfies him but frustrates his lover, who is unlikely to experience orgasm that quickly. Freudians claimed that premature ejaculation could be cured using psychoanalysis.
Premature ejaculation (PE) occurs when a man 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. Mens 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 men, women consider PE less of a problem, but several studies show that the condition also causes female partners distress. Cause
The causes of premature ejaculation are unclear. Many theories have been suggested, including that PE was the result of masturbating quickly during adolescence to avoid being caught, performance anxiety, passive-aggressiveness or having too little sex; but there is little evidence to support any of these theories.Several physiological mechanisms have been hypothesized to contribute to causing premature ejaculation, including serotonin receptors, a genetic predisposition, elevated penile sensitivity and nerve conduction atypicalities.
