Ah, my apologies for misunderstanding your post, then.

The way your sub acts sounds a lot like how I acted in the beginning of my D/s relationship, although she does sound a bit more feisty *g*. This is because I'm one of those who crave being 'forced' into submission. I needed to be put into a situation where I had 'no choice' but to submit, before I could truly submit. Fortunately, my Dom enjoyed gradually 'forcing' me into submission as well, so that worked out for both of you. My question before anything else is: do you enjoy such play? If you do, then read on. Otherwise, definitely sit down and talk to her.

As for the examples, I'm not really sure if mine would be of any help, as my relationship is online at the moment. But anyway, what my Dom does is clamp down really hard if I start rebelling -- disobey him directly even once, and face dire consequences right away. Consequences that I really would dislike, such as no playtime (which was what you did, and a brilliant idea IMO). And any protests/complaints I make about the punishment would be rewarded with additional punishment.

That sounded awfully vague, but I hope it helps. :P
