That seems high.

Durex's Global Sex Survey has found that 44% of adults worldwide have had one-night extramarital sex and 22% have had an affair[13][14]

Adultery in the United States

Alfred Kinsey has found in his studies that 50% of males and 26% of females had extramarital sex at least once during their lifetime.[15]. Depending on studies, it was estimated that 26-50% of men and 21-38% women[16], or 22.7% of men and 11.6% of women had extramarital sex [17]. Other authors say that between 20% and 25% Americans had sex with someone other than their spouse[18]. However, one survey that measured the prevalence of adultery in the 12 months prior to the study showed rates of extramarital sex as low as 2.5%[16]. The results suggest that while 15-25% of ever married Americans have had extramarital sex at least once in their lifetime, extramarital sex occurred infrequently in any one year. [17]
