Nonsense. We are a S/V couple. First of all, we make sexual decisions in this area together, she is sub and I am Dom (not black owned), she isn't a QoS, I actively participate in the sex when I want, we have sex alone together, there is no cuck humiliation, and many more things. Dynamics are totally different.
See, you didn't look at the definition of "cuckold" before you wrote. A cuckold is the husband of an unfaithful wife. It doesn't matter whether you are dominant or not, or whether you're humiliated or not. By definition , you ARE a cuckold. The fact that you have added power exchange to your relationship doesn't change the fact that you're a cuckold.
Mainstream porn has made you believe that you have to be submissive or be humiliated to be a cuckold. You have been misled.
