I am just throwing this out there ... as my experience only and am sharing it so you might learn from what I went through. I love my wife it was her idea to swing and I took the. All and ran with it when we got serous about doing it.
We had many rules when we started, her more than me. No kissing was a big one and the pet names were to be kept between us as well. The first time we played a woman kissed me on the mouth as I was in the throws of passion and kissed her back.my mistake but it t happened. I am human that got milf was sucking on me when another came up and stuck her nipple in my mouth and when I was about to explode she put the lip lock on me... good bad timing for us all. My wife was hurt but by the same measure we said we would not do some things she said she would not do anything we don't do together and she got kissed by a man while I was eating her that same night. She didn't see me get the lip lock from carol I told my wife's out it later. We laughed and I thought passion can be powerful when you are in the middle of it.
Here is the rub. I did have the twang of jealousy as I watched my wife not only get kissed but fucked as well. Hell she was riding this huge guy and having the loudest orgasm I ever heard from her and thought why doesn't she do that with me. Then as she came she kissed him.
It was my feelings that were in the way. I thought I was the only one that could make her feel that way and I was wrong. Every person we invite into our life effects us differently and it's how I choose to react to them that makes the difference. If I let my jealousy speak I would have maybe lost forever the chance to swing with her again.
I respect my wife enough to let her have those experiences without letting my ego and misplaced feelings get in the way of our pleasure.not just sex and swinging, life as well let your partner fill his or her life with their love and beautiful things will grow in your relationship.
If I give her the same chance to experience her fantasies I get to experience her joy in it and my experiences too. Turning that jealous twang into a harmonious accord is the point that launched us onto an amazing sex life of free sexual expression that changed our lives and helped me be a better man.
Build this new part of your relationship on positives rather than mistakes.heck one of or best memories of swinging isn't the sex it's the journey now my wife and I are nearing our fifties and the friendships memories and the fantasies left untried are still pushing us ahead and if my wife asked I would let her do anything and that came from the respect we built not from honoring rules but how we treated each other when we failed!
Sorry for the poor edit
