Studies universally suggest that somewhere between 10 and 20 percent of people in committed relationships sexually cheat on their spouse or significant other. Of course, in today’s world of chat rooms, webcams, instant messaging, and instant pornography, the concept of cheating is, in the minds of many who do it, somewhat malleable and easier to deny than in the past, when cheating meant actual live physical contact.
So in consideration of our evolving Internet definitions and experiences of cheating, it is likely that 10 to 20 percent number is an underestimate.
While our cultural stereotypes tend to focus on men stepping out on their wives or girlfriends, the fact of the matter is almost as many women are unfaithful as men. It does take two to dance the infidelity tango. Some women stray sexually when seeking some form of deeper romantic connection or emotional support seemingly missing in a primary relationship.
But many others will cheat for the very same reason most men do: they just want more or better or different sex.
