i think there might have to be two (or more) models to make them simple. There are those whose relationship is more kink oriented D/s, and some whose is more service oriented D/s. Then there are those (like mine) that blend the two without there being a strict line of demarcation. No one kind is better or worse than another, just different.

Then you can throw in Switches, masochistic Dominants, and all the other variants out there.

Oy, the mind boggles. i think i just gave myself a headache.
