One study of married heterosexual couples in America showed that 23.2% of men cheated on their current partner. [1]

  • For women, the same study indicated that 19.2% of women also had sex outside their current relationship. [1]
  • In Western countries, between 25 and 50% of divorces are primarily caused by partner infidelity. [1]
  • 72% of men who reported cheating also reported lower levels of relationship happiness compared to men who did not. [1]
  • Similarly, 62% of women who engaged in infidelity reported experiencing lower relationship happiness compared to women who did not cheat. [1]
  • A survey of social attitudes in China showed that 74% of women and 60% of men stated that infidelity in a marriage or while cohabitating with a partner is completely unacceptable, and either somewhat or completely unacceptable to 95% of women and men. [2]

Gender and sexual stereotypes may lead some to assume men cheat more than women, and while the stats do agree, the difference is fairly small.

Who Cheats More, Men Or Women (Dating)?

  • One survey reported that 23.4 % of American men in dating relationships cheated on their partner sexually (face-to-face). [4]

  • 15.3% of men and 4.6% of women reported cheating on their partner through online means, with no physical involvement. [4]
  • Both men and women who have a past history of cheating on a partner were found to be more likely to do it again. [4]

Do Men Or Women Cheat More With Their Friends?

  • Statistics on cheating tell us that over half of women (53%) who have affairs do so with friends, compared to 32% of men. [3]
  • Are men or women more likely to cheat with coworkers? Sexual relationships begin at work for 44% of men, and 32% of women who have extramarital affairs. [3]
  • Meanwhile, 37% of men have had an affair with a stranger, compared with just 9% of women. [3]

Women appear to prefer a more personal connection with their cheating partner compared to men.

This makes sense considering that on average, many women tend to prioritize an emotional connection with a sex partner more than men.

Do Women Or Men Cheat More In China?

  • During a one-year period, 4.5% of women had extramarital sex. [2]
  • For men, that number was 16.5%, with 5.5% engaging in commercial sex with a sex worker and 11% non-commercial. [2]
  • In comparison, 74% of women and 60% of men reported that extramarital sex was “completely unacceptable.” [2]
  • 77% of women who took part in a survey “wanted severe punishment of men’s short-term commercial sex” (cheating with sex workers). [2]

Cheating with sex workers occurs almost exclusively among men.

While occasionally women may frequent sex workers, by and large, men make up the dominant customer base, so the gender difference is unsurprising.

  • One survey reported that 20% of British males have had sex with someone who wasn’t their primary partner. [3]

  • Cheating statistics tell us that 35% of men and 44% of women from England who had affairs did so because they liked the attention and found it flattering. [3]

British men are more likely to cheat than women, but the difference is small.

Forgiveness after cheating is always difficult, though while we culturally tend to assume women are more empathetic, British women appear less likely to forgive after infidelity than men.

While online dating has been around for decades, smartphones, social media, and dating apps make the process of online cheating much easier and more accessible.

Timothy Robinson, a dating expert at OneNightFriend, told us “It’s important to note that not all users of dating apps are engaged in infidelity.”

“There are many trends like open marriage or monogamish relationships, so technically these interactions cannot be considered as infidelity in the respective cases,” he explained.

“Also, some users can be satisfied with simple online communication,” he said, adding that satisfying one’s craving for attention or a boost of self-esteem can be achieved without actually seeing other people in person.
