Being submissive is completely about being able to trust someone THAT much - if that someone is inconsistent and unpredictable how can we trust them with our submission. Subs want to feel safe and looked after; we need to know that even though we aren't in control of the situation the situation IS under control. I love knowing that I can 99.9% of the time predict his reaction - if I’m testing the boundaries chances are I’m not testing them because I am oblivious to where they are but because I am testing his consistency. In my eyes being consistent and predictable (In your reaction to situations, not necessarily in what’s to come I scenes) is the only way to earn a subs total trust and submission. Submission is NOT an easy thing to give up, and yes, sometimes it needs to be coaxed out of us, but as a Dominant you need to be consistent and patient - so that when your sub is ready to give it up completely, they can -- and will, and if its as perfect as it is for me, they'll never want it back.
