We follow the main trend this thread shows. We started out with more than we have now. Mainly now it's go with the flow, respect each other, and communicate.
We've pretty much just said 'no rules anymore' but it's because we understand each other so well. We still stay 'same room' but if the desire came to go to seperate rooms we'd know it - just by a look or nod of the head. We don't restrict each other, but we truly enjoy the same room so we can experience pleasure together.
We also say 'condoms only', but we've broken (no pun intended) that rule too, with people we know and trust.
