Despite what reddit would have you think, most cheaters are male. The empirical evidence backs this up

Most men are biologically programmed to want to have sex with a multitude of partners whether they have a partner or not. A lot of marriages don't work out because people can't reconcile their romantic monogamous desires with their polygamous sexual desires

This creates issues because most women are romantically and sexually monogamous in relationships. Despite what people read on reddit, most western women will be disgusted if you suggest a one-sided or doubled sided non-monogamous relationship. They want their male partner to have exclusive sexual rights with them

When women cheat, it's generally because the loves gone or they'll create some narrative as to why it's actually okay. Men just want to fuck
