Like R&K, we know in 10 minutes if it's a go. You can sense it. Well we can. We can also tell if it's a go for them.
But even great conversation and the illusion that you are all compatible for a 4 some. She (one of the she's) might end up "taking one for the team". If the other guy can't get hard. Or doesn't know how to turn the other lady on, that lady is taking one for the team.
But sometimes the date gets better with time. Although, my wife is opening her options bi playing on both teams.
We always talk about the session on our way home. More than thrice, she has stated, "What was I supposed to do with that?" I just smile and reply, "OMG, she was so fucking hot. You should have played with her"
But it's all good. Don't look for the couple in the mirror. You already have that.
In closing, just relax. You might have a totally new experience. And THAT'S what this journey is all about.
