Thanks for the responses all! While I am very new to this, my SO has experience with the lifestyle in the past. I don't know if she is introducing me slowly to this or if she is truly happy where we are at (she is awesome!). I have asked this question many times in many different ways but always the same answer, "no, I don't want to involve anybody else".
We do go the the couples room, have played in the same space with others, talked, watched and were watched by the other couples. She is really good at setting boundaries with others, so far, its working well and we have a great time.
But it does sound like we are in the small minority!
