If she consistently talks back and disobeys perhaps the submissiveness level you desire is not within her. I would question why i had problems with her level...
Was it my own desire of control ?
Why did she feel uncomfortable in giving you that control ?
If the submissive one isn't willing to give it then all the punishment in the world will only end up creating a wedge in the relationship.
Find out more definitively where her boundaries are and if they are within your parameters.
Then you would have to learn to work within the boundaries of that relationship.
That is how reality works regardless of what one may wish it to be like.
Just my opinion.
