Such an excellent thread, very well put together.
I've found most women enjoy self-degradation, to be told how they're going to be fucked like a dog, a slut and such words. Knowing what pushes them, their fears and kinks, a very wise Master can use such knowledge to test the limits if not expand them. Its' one of the most basic aspects of the BDSM life style.
If you can get into the mind of a sub or slave and know them better than they know themselves one often finds they truly own them.
