I spoke to a therapist about this. They said that it is a pretty common mechanism that the mind will use to provide a sense of control to someone that has been cheated on and still has trust issues.

So the way I understand it, is if you were cheated on and have trust issues, watching cuck porn helps your mind feel like it has control of that emotion?

I don’t have that issue, but I do have PTSD and my mind does some really weird shit sometimes to make sense of problematic emotions.

So, it seems logical to me that this could be true, considering my own experience with my brain’s subconscious mental gymnastics.
