Goodtimes hit the mark and did a good job of summing up what I think everyone else has been saying.
If it ain't there, it ain't there.
It boils down to whether the "nice" couple also fits the mark for sexual attraction. We've met tons of nice people but nice plays a small part in swinging. Rejecting people who aren't nice, that's easy and understandable. But most people are nice and they're all over the place; still, people don't play with others just because they are nice. You've got to want to have sex with them and that desire either strikes you or doesn't.
For us, I can't give a pinpoint reason why we aren't sexually attracted to them because the reasons are varied and unique to each situation and some people have given us multiple reasons others only one...bottom line,we just didn't feel like having sex with them.
Trying to break down your question into trends and common themes feels way too technical to me, and I can't get into tech stuff when I'm thinking about sharing my naked body with people. LOL Sorry, it just takes the fun out of thinking about swinging. Maybe it's because I've always approached swinging on a very instintive level and so making a list of pros and cons about a couple before deciding to have sex with them has never been my thing.
From what I've gathered from your posts thus far, I wonder if you're trying to break rejection down so that you can suggest what swingers need to do to change or improve themselves in order to avoid being rejected. Here is the problem I have with that idea. I have seen way too many swingers try to become something they are not in hopes of making themselves more unrejectable to others. This can work against them in that they actually lessen their self-esteem, rather than becoming more comfortable with themselves as a swinger they are constantly striving to improve themselves and become someone that isn't themselves. I see people trying to do one more thing better to make people want them more: boob jobs, losing weight, tummy tucks, hair removal, facial plastic surgery, hair color, building their bods into muscle, wearing clothes that they look stupid in but they think others will like them better in them (yet they look so uncomfortable wearing them) and I could go on. Some of these changes can be put in place without pressuring yourself (like waxing/shaving your genitals) but other decisions for improvement I doubt would have ever been done if they hadn't become swingers.
I have to wonder, how happy can some of these people be if after they make some of these changes they are still getting rejected? And they WILL still get rejected.
