He said he was ashamed that porn had made him partially disengage from his flesh-and-blood, dearly beloved wife. It was not a small thing to him. It seriously undermined the satisfaction and contentment of his marriage. He had to consciously work for years to get rid of his porn-mind.
I knew a woman who was married to a wonderful man and in a good marriage. She once told me that because of her previous exposure to romance novels, Hollywood movies, pop music, and feminist indoctrination she could not clear her head of weaponizing sex against her husband. She wanted to control him and using his sex drive was easy. On the rare occasion she subjected her self to have sex with him she was disappointed that he did rip off her bodice like Fabio did and she felt she deserved.
She was never ashamed and when her husband who did not desire to destroy the marriage, he turned to porn as his only sexual expression that did not include a real flesh and blood affair. She blamed him for her frigidity, after all she would respond of he made her happy. She believed that he did not know to have sex with a real woman, because of porn, and his expectations for her were all just patriarchal porn fantasy.
He knew his marriage as the old celibacy. But his wife blamed everything on porn ignoring her own refusal and contempt. She was supported by many conservatives and Christians who demonized porn as the great sin of our age, but divorce, frigidity and wifely contempt are just peachy.
Shoe meet the other foot!
