My thought is that you are jumping ahead of yourself, and I would recommend that you just enjoy each stage of the relationship as it comes, rather than trying to plan too far into the future.

Enjoy just getting to know other and exploring each other's natures first, see if she agrees that she would you to help develop her submissive side, discover what happens if she does etc first. This way you will ensure that the foundations of any future relationship, of whatever nature, are secure.

Wishing you a happy future,
