If I had seen this question perhaps like twenty years ago, I would definitely say that men cheat more. However, in modern times, I would say that it has almost become like a competition for the trophy. Women now cheat as much as as men did. I think, though I stand to be corrected that one of the reasons men cheat has a bearing from male entitlement. Somehow some men feel that their gender gives them that automatic right. Especially in cultures where polygamy is accepted. After all it is wooing before a wedding. Plus the men used to be the sole providers hence they did what they deemed fit and no one counters. Now things have changed. Women work as hard as men so they believe they should have equal rights in everything. Perhaps the right to cheat too.
