Quite useful as a starting ground for discussion about wjhat kind of relation you're in and what is wanted. I'm sure it wasn't meant to be seen as a sort of definite Holy Writ about what kinds of submission there are, nor as a ladder ("you start at level 1 and become more and more accomplished"). Most of us have been turned on at the start by the ultimate, fantasy-like depictions of BDSM, like The Story of O and stories of kinky dungeon life (or by the glamorous seventies?); whether you find those around in your neighbourhood or not, it's useful to consider how much and what of the "package" works for me, for us?
It would be nice to know when this was written? It could apply to both online and real-life D/s, but the possibilities of online contact in realtime (web talk, Skype, instant sharing of reports and images) have transformed the BDSM world, and this has really happened in the last ten years.
