Swing
Interesting... The first thing that came to my mind was "swingers." I recently had a conversation about open marriages - I'm not married. It wasn't about me! We were actually talking about cheating spouses, and a situation that involved a wife repeatedly sticking by her husband despite his history of cheating on her.
I'd said that if they'd had an open marriage and were both ok with that, his actions wouldn't bother me so much (not that it's any of my business either way.) Then I said, maybe they DO have an open marriage and just never told anyone. Then I realized that, if he keeps cheating, and she keeps sticking by him, that's exactly what they have. An open marriage they're both ok with.
