Okay, I have little BDSM experience but I do have an opinion which is worth what you paid for it!

1. Being demanding in scene.
2. Scripting out every single moment of the scene in pre-scene discussion/negotiation.
3. Using the safeword to get your dom to move on to something you like better, rather than as it is intended.
4. Being derogatory about your dom's abilities in after-scene discussion/check-in.

These are just my ideas, based on a lot of research and reading in the last few weeks...I haven't had very much opportunity yet to put the non-use of these principles into practice yet, although I am working on the concept of shutting my mouth when I don't have something positive to say!
