Chastity and orgasm denial discussion

It’s a very simple question for all you married/attached chastised men out there. What is it worth to look at porn - especially if it’s a type of porn that your KH has explicitly forbidden? For example: My guy knows that Femdom/Chastity porn, GIFs and captions are ok but he will sometimes go to his old standby (traditional BDSM with the man topping). This naturally upsets me since he knows that is the one type of content I do not allow. Do you do it to get a rise out of your KH? Do you do it in a moment of weakness? Do you do it just to defy Her? Do you do it because you are horny and not allowed release? All answers welcome except for answers that attack me. Thank you.
