I also "couldn't perform". Not so much because of the "mind movies", although I had them. My issue was that she told me how the OMs anatomy was larger, he had a better physique, and he was better in bed.
The total disgust has not passed away. Even 27 years later, that's exactly what I feel when I think about her.
The sex life didn't "dwindle", it just abruptly stopped one day. I regained my "performance" a couple of times, and the day following, she made a comment about "you finally acted decent" or something to that effect.
It was like I heard an audible "snap" in my mind, and I remember saying to myself "well, I sure hope you enjoyed it, because that's the last time you will ever get it". And, it was. I had no desire at all for her. If she was the last woman on earth, I would seek the priesthood or something.
As for her feelings for me, she admitted a couple years down the TT path that she had only married me because I was willing to raise her quadriplegic son as my own. So, there were no "feelings" to come back.
My anxiety attacks subsided over a few months.
I missed the smell, touch, etc of a woman, but not her. She made me want to throw up.
