What Is It?
Here's the thing: monogamish is what you call it when you're mostly faithful, but you've both agreed the rules don't have to be absolute. Sex columnist Dan Savage coined the term around 2010 to describe his own marriage. His exact words? "Monogamous with a little squish around the edges." And honestly, he nailed it.
The key word here is occasional. Monogamish couples don't maintain ongoing outside relationships. They might have a hall pass during business trips, enjoy a threesome together once a year, or have other specific arrangements that work for them. Between those rare exceptions, they function like any other committed couple.
This sits between strict monogamy and fully open relationships within the spectrum of ethical non-monogamy. Unlike open relationships, which allow ongoing outside partners, monogamish arrangements maintain clear primary relationship focus with infrequent exceptions. The primary partnership remains the emotional and romantic center. Outside encounters happen rarely and follow pre-negotiated rules. For many couples, it's a release valve that actually strengthens the main relationship by removing the pressure of total exclusivity while keeping the foundation intact.
The Spectrum
| Level | Stage | What it involves |
|---|---|---|
| hall pass only | Hall Pass Only | One or both partners can act on opportunities when traveling alone. What happens on business trips stays there. Everything else remains exclusive. |
| together only | Together Only | Outside experiences only happen with both partners present. Threesomes, soft swap at parties, or other shared adventures. Solo encounters are off the table. |
| special occasions | Special Occasions | Specific events trigger permission. An anniversary trip, a birthday gift, attending a swinger event together once a year. |
| don't ask don't tell | Don't Ask Don't Tell | Partners have agreed-upon freedom but don't discuss details. They trust each other to follow the rules without needing a full report afterward. |
| custom rules | Custom Rules | Every couple builds their own framework. No colleagues. No repeat encounters. Only when the other partner explicitly approves each situation. The combinations are endless. |
