"We are that kind of couple" is not an answer

A label can be helpful. Hotwife, stag, cuckold, open, curious, monogamish. It's nice to discover vocabulary for something you've been trying to explain. But two people who use the same word can mean very different things. Do they want to meet people? Talk about fantasies? Share photographs? Keep it entirely private? Ask about actions and limits before you assume the label tells the whole story. Real relationships have more settings than a dating site's filter menu.
