I would say men are more likely to cheat but women have way more opportunities to do it, so the end result is about equal or more on women's side, specially if you remove prostitution as an option (which has been stigmatized in some countries for the last decade or so). But this is just generalizing, at the end of the day people are individuals. Although a lot of the anti cheating crew are either lying or have little to none opportunities to cheat and try to sell it as a virtue (it might be my cynicism talking).Thank you! The stupid never ending arguing between men and women is about who cheats more, when actually they do it equally.
