I have heard it said, and I wholeheartedly agree, that "BDSM without emotional attachment and a deep relationship isn't BDSM at all; it's just kinky sex."

I think those words were uttered by the great and powerful Oz, actually.

As for poly relationships, if I was ever do be involved in one, it would be the opposite of walls- there would have to be no walls, between all of the partners. The only way I would see it working (for myself) would be to have complete honesty and trust between all partners involved, and since two people have a hard enough time doing this, I imagine it would only get harder as more people were added.

I also think the idea of it extremely delicious. : D
