I'm totally fine with guys cheating. I wouldn't disrespect a buddy if he cheated, and would never tell. Women who cheat, on the other hand, are filthy whores and have no respect for. If I know a girl cheats I will tell on her to everyone. I know it isn't logical, but something about nature and the way we perceive genders in our society have left me with this mindset.
Better to be the bastard child of a king and his whore than to be a ****ing peasant at the shite homer trough.
