I appreciate the responses.
Fetish: LOL...I'm not the jealous type so I doubt that I can explode into a fit of jealousy and rage.
Clipcrop: I'm honestly not trying to solve the riddle of characteristics that will make for lasting human relationships (love your wording). I'm simply trying to understand why someone would pursue another when there are so many differences.
Wouldn't it be prudent to seek someone with at least some of your main likes, kinks, etc.? It's been my experience that relationships can be difficult enough even when you are compatible in most things.
