All is so true. This as in life, we meet people everyday. Having something in common is only step 1 in the compatability game, no matter what it is you are doing. I am a nurse, there are some nurses at work that I honestly can't stand, and they can't stand me, but we are all nurses. Which means we have a strong common interest.
But as I have said many times over, there is something that I like to call the "human factor", which is my generic term for human behavors that seem to be miss placed.
For example, two people meet on line in a med fet room. It seems that they both have the same indeals in mind as far as what their kinks are, they seem they would be a good fit, he likes a younger patient, she likes an older doctor and the list can go on and on. But once you meet them, and they even can be exactly as they said they were, and you as you said you were, but sometimes even with all this commonalities, you still are not a match. It's really quite the complicated thing.
Which is why sometimes people ask me why I am not "jealous" per se', but probably way more over protective of my relationship that I have with Doc than I should be or need to be. But, sometimes having everything in common, wanting the same things, same goals, same outcomes still isn't enough. There has to be a chemistry there, and it's the chemistry in which the relationship, if there is to be one, will grow from, not from the things you have in common. I am having a very difficult time articulating myself correctly this late hour,but maybe someone gets half of what I am trying to say here, lol.
