Prevalence
American biologist Alfred Kinsey found in his 1950-era studies that 50% of American males and 26% of females had extramarital sex. Depending on studies, it was estimated that 26-50% of men and 21-38% of women, or 22.7% of men and 11.6% of women had extramarital sex. Other authors say that between 20% and 25% Americans had sex with someone other than their spouse. Durex's Global Sex Survey has found that 44% of adults worldwide have had one-night extramarital sex and 22% have had an affair. According to a 2004 United States survey, 16% of married partners have had extramarital sex, nearly twice as many men as women, while an additional 30% have fantasized about extramarital sex. There were also studies that have shown rates of extramarital sex as low as 2.5%. As many authors conclude, these kinds of estimates are probably understated because extramarital sex is commonly disapproved.

“The prevalence of suicide, without doubt, is a test of height in civilization; it means that the population is winding up its nervous and intellectual system to the utmost point of tension and that sometimes it snaps.”

“That the public can grow accustomed to any face is proved by the increasing prevalence of Keith’s ruined physiognomy on TV documentaries and chat shows, as familiar and homely a horror as Grandpa in The Munsters.”
