Susan here-- You gotta love someone who quotes from 'Dune', thanks Chicup.
That being said, I had played A LOT before marriage and Ed had never. When he asked to try Swinging, we talked a lot about it. What he expected to see, what he thought the experience would be like, etc. And, despite outlining the experience, know that things never play out exactly as you think. Be open to diversity in your experience. For him, because he wasn't looking for trouble or jealousy or problems, he didn't have any. He did have an incredible night where the sex was so good the neighbors needed a cigarette.
In our case we had two couples over, that I knew,and Ed explains it like this,"I look and there's this beautiful woman, she's on all fours, one man taking her from behind, the other man is getting oral sex from her and they're having a great time and all I'm thinking is 'Yep, that's my wife,' and then I had sex with her best friend Kate."
I really hope that if you try swinging and do not like it , that you will not harbor regrets. I find it so sad when people have sex that they regret. An experiment that you do not repeat is fine, trying new things is part of life, but please do not have regrets.
For us, choosing to have fun and not have regrets, no matter what, made the reality much better than the fantasy. Thanks for listening.
