just something that perhaps you haven't considered. i am THE most impatient person alive and one thing that i have found in my very limited experiences with D/s is that when i am required to follow my dominant's timelines and schedules i get more out of it. it truly is fighting against my natural inclination and helps me to better experience the tease of the situation.
as a submissive it is sometimes hard for me to understand the "master" plan and if i ask it is his choice whether to share it or not.
you built this relationship on a foundation of common need and interest. assuming that he suddenly hasn't changed those needs and interests .. i see this as a test. as you said .. afterall you are the submissive and it is your desire to submit to his will and desire.
