Just1gurl, I thought the carrots were cute as an avatar. I used to live in DC when I was in the Army. PM me some time and we'll swap stories.
As for the rules...we had too many to start with. We wouldn't play with people unless they we had established a relationship with them first (which ruled out many of the people we were meeting at parties). We even had rules about what our play partners did for a living.
Now, we try to keep each other in mind so as to not bruise any feelings. We each have "veto" power over any potential playmates. We make sure that we each know where the other is at all times. I feel that my first job is to keep Mrs. DD safe at all times. Secondly, I want her to have the best time that I can provide for her.(remind me to tell you about the dance sometime) Lastly, I look to my own pleasure. It seems to be working so far.
