To the original poster I'd say it all depends. If you enjoy the status quo don't do anything. In our case we established early on that cheating was out of bounds but she also had a hall pass. Some people need secrets to get excited, some people have partners that can't handle the truth (that we want to fuck other people. I think lots of people make it work lots of different ways. I woud not want to be cheated on. I've always tried to give my spouse enough grace that she would never need too. That said if it happened I think I'd be more forgiving than vice versa but I think that the way more woman than men are wired. Would be great if this was an opportunity for her to share with you and develop a better relationship. Good luck!
