When we started, we had more or less equal experiences all of the time. This included MFM about half of the time. I always enjoyed that so much that I didn't care that I was not screwing a different woman. We never thought about "fair and balanced" experiences until the night my wife had two different encounters (without me) and I had none. That was the first, and only, time I ever thought about being short changed. We talked about it (as we did about anything that ever bothered us), and decided that she would never have more than one other guy in any evening unless I was playing also. That is the only explicit "rule" we ever had in swinging. Otherwise, (just about) "anything goes," and we usually had a great time.
