Discipline is rarely enjoyable for the submissive while it is taking place (although if it induces subspace, it can be erotic and mentally and spiritually fulfilling). The cane and the paddle hurt and discipline can be uncomfortable. But afterwards, it yields the peaceful fruit of love and surrender.
The reason your mood changed after five or six painful blows of discipline is because it was at this point that you surrendered to her and once you surrendered to her, you were able to enter subspace. I am convinced after talking and communicating with so many submissive men over the years that there is no better experience for a man than that feeling of surrender to a woman. It produces peace and a feeling of being loved. It is intimate and romantic. It is spiritual and it is what the heart of man needs and longs for.
The strap-on is a further extension of the surrendering process. I think the strap-on is the perfect companion to the discipline session between a wife and her husband. First comes the discipline to get the male in the proper frame of mind, to get him to surrender his male ego. Then comes the strap-on to enforce that surrender. My, what a bond of intimacy and true female domination the paddle and the strap-on can bring to a relationship.
