I'm wondering what the RPW opinion is on D/s relationships?

I find it interesting that the world has moved so far that things like "50s household" and "Taken in Hand" are now kinks, instead of the natural way we do things.

Personally I found delving into the kink world of D/s significantly improved my relationships as I found that kinky people, being so far to the edge have really worked on clear roles and clear communication. Going so far as to have basically rule books for the relationship (not written in stone, but revisitable)

Applying all that knowledge as useful to a less kinky relationship has worked for me. Just wanted to hear others experiences.
