Female-led relationships. Again, I like the male submissive / Female dominant aspects. i like the idea of serving Her. And not just doing the traditional female household activities. The trick, i think, is in the attitude. She leads because She wants to, not because i want her to. i submit because i want to, and She enjoys it.
Spanking is another aspect of Female dominance. Spanking is such a cathartic activity for both parties. The spanker unleashes physical and mental dominance over the spankee. The spankee in turn endures and enjoys the physical and mental domination.
