VeezKnight has written a fine post about reinforcements in female dominant, male submissive relationships, marriages:
Less overt daily reminders can therefore become very important. I don’t think that a woman who is growing into her dominant role in a relationship initially appreciates the importance of this. I also suspect it takes a while for her to fully comprehend that it is not necessarily a dominant act itself that makes things click in the submissive male’s mind, but rather, it is how the act makes him feel.
