We almost always start
same-room only no 1:1 with any new playmate. It's a comfort and safety issue.
After we get to know someone we may do seperate rooms but really prefer same room. It's a matter of "we like to watch each other have fun..."
It's also a matter that we like the third and fourth player interaction. I can have 1:1 with hubby -- me and hubby alone can't do MFM or FMF or MFMF -- those require same-room by their nature.
Now, we have done a complete swap twice. By complete swap I mean we went home with each other's spouse - once for a weekend and once for a whole week. That was kinda fun but it wasn't "swinging" it was "swapping". I'd imagine such an arrangement wouldn't work for everyone.
So, for us it's not about trust when we ask for same-room but it's more about what we are looking for in fun. You can't do a DP when one of the guys is in the other room....
