Non-Monogamy 

A sexual relationship that doesn't disallow sexual expression or affection with other partners. This may present itself in many forms and many kinds of lifestyles including but not limited to swinging, polyamory, polygamy, open relationships, or simply couples having an occasional -threesome. Yes, even if you romantically kiss only one other person while in a sexual relationship with with someone else, you are exhibiting a behavior that is clearly not monogamy.

We're mostly monogamous but sometimes we like to invite another woman into our bed, so I guess that makes us non-monogmists.

Every year we get crazy and allow each other one night of non-monogamy action.

A situation in which two people decide that they want to be sexually exclusive without taking on the title of "boyfriend" & "girlfriend" or having any type of official commitment. Often following a period of transition between casual dating and an established romantic relationship.

"John has been with that girl for a few years now. Is he ever going to start introducing her as his girlfriend?"
"He's afraid of commitment and happy being in a monogamous non-relationship. I don't think they are going to put a title on it any time soon."
