Monogamy | Unpopular Opinion

So i just saw this video and i know that everyone is entitled to their own opinion but i have to be honest, this one just rubbed me the wrong way. I know that women are wired differently than men but it doesn't sit well with me when some people say it's IMPOSSIBLE for a man to be faithful to only one woman. I'm fully aware that some women here may disagree with me on this but i will ask anyway. How many of you actually believe that ALL men cheat? How many of you are in relationships and your significant other is actually faithful to you? I can't be the only female who believes it should be ONE MAN and ONE WOMAN.
