I really don't have anything particuarly good to add here...but felt I should throw in my .02 worth anyway. lol
First of all, the other people's reactions may have nothing to do with you. While you may think everything went well...and it may have for that evening...maybe they aren't into having repeat partners.
I mean, I get the feeling that what you describe (having bascially a circle of friends/acquaintances that play every so often...not necessarily exclusive, but repeat performances) is the ideal for many swingers...but quite a few people really just aren't looking for that.
They are here more for the variety and tend to take a 'been there, done that approach'. If it was a good experience, they'll take it an go with it. Why? Because the next time may be too familiar and not as exciting for them...so why diminish the original awesome experience they have had with another experience that may not be as intense or amazing in their eyes.
The thing is, some of the questions you posted up in your original post...did I not fuck good enough, dick too small, wife not attractive enough, etc...honestly, would it make you feel any better if someone did answer those questions? I would take it as more of an ego blow to be ripped apart like that instead of just chalking it up to 'eh, their loss if they don't want to play again'.
I do think your expectations are too high...but maybe you do need to change up your MO...you may not like the clubs, but go. Starting your own group around an activity or house party is a good idea that other posters mentioned.
As for your presumption that some people may not have their shit as together as y'all do...you may be right...but there are plenty of people that just take a 'go with the flow' attitude and let that guide them rather than being overly specific in what they are looking for.
Good luck!
