Our first swinging experience was probably done the wrong way but it had GREAT consequences. We jumped in to far to fast and had a full swap (same room) with a couple we met online. It wasn't horrible sex or anything but I think we were too naive to know what was really happening.
The way home the next day was very tense. HOWEVER....once in our own house the communication just opened like a floodgate. We learned more about each other in three hours on a Sunday afternoon than in the prior two years of our marriage. We had talked a lot about this choice beforehand but I don't think anything could have prepared us for the reality.
I don't want this to sound like a bad story. As I said, I wouldn't have changed the outcome for anything in the world.
