You know you're a cuck when after a number of casual suggestive conversations about my wife and other men, you then suddenly discover her being involved in an secret affair with a married older man. Couple of weeks later after dealing with the emotions of her deception, finally calmly sitting down with my wife to try to discuss the "situation". Eventually we mutually agree that going forward she may enjoy the intimate attention from other men (including the current lover) that she finds to be attractive. It is understood that she has my full consent and there will never be any negative comments directed towards her as a result of this agreement. I promised to not to interfere with any related arrangements and would do whatever is reasonably necessary (ie: watch our children, run required errands, do household duties, take time off from work, etc.) to allow her to take full advantage of any circumstances that will facilitate her communicating and/or meeting up with a lover. My wife agreed to provide me with those details "that she feels" I should need or may want to know, but insisted she not be subjected to intense questioning concerning particulars she might desire to keep to herself.
Also as part of this arrangement I consented, at her insistence of forever forfeit becoming intimately involved with any other woman. It is mutually understood that our agreement is just a one way privilege enjoyed only by my wife. Any future conditions that might enhance or expand this arrangement will only be made by my wife.
I think when I proposed this and after some negotiations, where we both subsequently agreed to the conditions was when I became "officially" a cuck
