Slave2Catwoman describes the feelings being cuckolded arouse in him:
During these experiences, I go through every emotion possible. Happiness, sadness, anger, jealousy, insecurity, fear, sexual excitement. It is incredibly arousing to be so openly used and degraded. The fact that she makes dates while I am in the room with her is so humbling. She has no fear that I, or he will utter even the slightest complaint. It is the height of disrespect to me as a man and just as a person. But I cannot deny that seeing Ms. Catwoman exercise her power in this way turns me on like nothing else. She can’t be ruthless enough, as far as I’m concerned.
