It had become obvious that your sexual inadequacies were putting a terrible strain on your marriage, so you and your wife decided to go to a highly recommended marriage counselor -- and by following the counselor's advice for your wife to begin cuckolding you, the strain between the two of you has been reduced dramatically.
The words every cuckold loves to hear.
Your wife knows how much it pains you that she dates and has sex with other men -- in part because she does it openly, so all of your family and friends know that she cuckolds you. And she also knows how humiliating it is for you to have to pick her up after she has been with another man. But none of that matters to her. It's simply something she needs, and that you know that you have to accept. You still love her -- and consider her the one true love of you life -- and so you accept that your role in your marriage is to be as supportive -- and unquestioning -- a good cuckold as you can be.
Your wife's always been pretty open and honest. So now she's just telling you how it is.
