42 Cheatin' Facts About Infidelity

Infidelity is as old as monogamous relationships, and it tempts and plagues even the healthiest couples. Read on to discover 42 truths about a primal and mysterious human condition that has likely touched every relationship in one way or another.

Infidelity Facts

42. Biologically Speaking

Of all the mammals on earth, only 3% are monogamous. Humans can count themselves among this group—for the most part. Interestingly, our closest genetic relatives, primates, are not monogamous.

41. Sudden Coital What?!

Men who cheat are more likely to suffer from a heart attack, or "sudden coital death," during the affair, as the man is usually in an unfamiliar setting and in a heightened emotional and physical state.

40. Definitely a Downside

Straight men with larger penises are actually more likely to be cheated on by their wives. In one study, for every inch Kenyan men had on their genitals, their likelihood of being cheated on rose by 150%.

In one survey, 42% of cheaters claimed that rock n' roll music was their favorite genre. Only 2% of rap fans, 3% of gospel fans, and 7% of classical music fans in the survey were cheaters.

30. Just Getting Started

The most likely time for an affair to arise? Two years into marriage. This is around the time couples start to settle down, build a family, and forge a life together. In other words, it's a time where romance can take the back seat.

29. Out of Sight, Out of Mind

Business trips set the scene for infidelity to occur. About 35% of men and women admit to cheating on a partner while away for work.

26. Sugar Daddies Left Behind

25. More is Less

It's not all great for women looking for a Sugar Daddy, though. Although in general the more money men earn relative to their spouse, the less likely they are to be unfaithful, this stops once men reach the threshold of bringing in 70% of the household income. At this point, men become as likely to cheat as before.

24. More Money, No Problems

There's no downside for boss women: Women with a higher income bracket than their spouses are also less likely to stray and they are likely to remain equally faithful no matter what their income is relative to their spouses.

23. Lucky Number 9

Men whose ages end in the number 9 are the ones most actively seeking a little something-something on the side, particularly if they are about to turn 40 or 50. This could very well be their last chance to potentially have a romance outside of their relationship.

21. Your Stairwell or Mine?

Of the hospital cases of fractured penises, an estimated half of these injuries occurred during an extramarital affair. As with "sudden coital death," researchers theorize that this overrepresentation is a result of extra excitement while engaging in sexual positions, often in small and awkward places. No word on how many male cheaters suffered from fractured penises AND sudden coital death.

Common Fears FactsShutterstock


20. Difference of Opinion

When a woman cheats, it’s usually for emotional satisfaction, whereas when a man cheats, it’s usually from a physically sexual motivation. In perhaps telling results, men also believe sexual cheating is worse than emotional cheating, while women believe the opposite.

5. The Danger of Being Caught

The guilt of an affair can weigh so heavily on a cheater's conscience that he or she may want to be found out. As Scott Haltzman, a clinical professor at Brown University, says, "Whether it's lipstick on the collar or emails left open on the family computer…it's a cry to say 'I need to get help.' Some people make it obvious because they want to stop but don't know how."

1. A New Hope

It is possible to repair your relationship after infidelity, but research suggest the the only way this is possible--according to family counsellor M. Gary Neuman--is if the unfaithful party feels remorse. Additionally, the cheated party has to trust the cheater and believe the affair has completely ended, and the victim should stay away from sensitive questions about the affair.
