So, me and my fiancee recently did Mojo Upgrade. In addition to some interesting new twists for things we already do, we also learned that we're both really interested in going non-monogamous. While we're not interested in polyamory, we're both really interested in bringing other people into the bedroom and we're going to try out swinging sometime. Any ADISC'ers ever do anything like this, in any capacity? What was it like for you?
