Reply To: Am I a good cuckold?

People have the need to both dominate and be dominated. You submit to your boss but you dominate your staff. There is a pack hierarchy. Women like to be dominated because it is bred into the race – when conquerors won the ones who would not submit got killed off while the meek served, survived and were bred. Sex is associated with breeding and since the women were bred by the stronger or more successful male it is sexier for women to be taken and submit to an aggressive male. The hunter/fighter was usually the male so we have evolved to have more dominant men while women evolved to accept and even seek to be “taken” by the strong. To a degree.
Women also want kindness, comfort and safety – part of raising progeny since a woman can only have a limited number of kids so must nurture them. The first part of survival is the long term satisfaction of basic creature needs: Food, shelter, security, and social/emotional support. They seek a “caretaker” first. Once that need is satisfied the need to be conquered, to submit to the stronger “Alpha” can emerge as a sexual desire.
Your wife has you for the first security, exhibited by your support and tenderness, and her Ex for the sexual excitement. She sucks you dick (lucky you) because she appreciates you and loves you for all that you do for her. She loves to suck his dick because she is turned on by feeling she is forced to submit to anything he wants.

That is the simplistic explanation but I hope it helps you understand your wife.
