Stepmom/stepsister porn

What are your thoughts on if you found your husband specifically searching for step porn? We hardly ever have sex and it’s not for the lack of trying. I even offer just bj’s so he doesn’t have to do anything and he doesn’t want it. I get turned down all the time. he’s definitely got some kind of addiction to it but to specifically look for that type? Idk how to feel about it. Every time we have sex, and I do mean every single time, he has to have me rub his back or massage it and then his belly. Or we won’t do it. He has told me before that his mom used to rub his back all the time and he says he loves it when I do it? I just don’t know..
