Yes, it’s very destructive of relationships for many reasons – not just because of the element of “cheating” which you mention, but also because of the unreal nature of the images and the artificiality of the experience, which then unconsciously intrudes into the marriage bed in a toxic way.
I do not have difficulty understanding how, once frequented with any regularity, porn can become “addictive” or a substitute for The Real Thing. I have difficulty understanding why people need to click on it
in the first place, particularly if you’re married with halfway decent communication with your spouse, and there remains a fundamental mutual attraction. How is masturbation “better” or more glorious than the erotic responsiveness of a live partner, which should be the best aphrodisiac ever? I don’t consider myself a model or something, but I’ve never had trouble keeping my husband sexually attracted to me.
In the “olden days” haha, people in truly loveless or sexually barren marriages sought either live affairs, or movies/videos, even massage parlors, and that was usually when the woman (especially) had completely lost interest in sex for valid or invalid reasons. (Correspondingly, a woman, particularly a rich woman, might seek a jigolo or an affair.) But it wasn’t the norm, necessarily. It wasn’t the dominant thing to seek extramarital stimulation on a regular basis, for a large segment of the population. That’s the part that I find so troubling: the danger to marriages on a large scale, which is unprecedented. And many of these women to whom this is happening are lovely, shapely women who are still young and sexually capable.
I guess it can only be explained as a case of curiosity and availability, combined with an abundance – a saturation – of erotic imagery in general in our culture, and a constant message that one can never get enough pleasure, and one must seek pleasure desperately and regularly, or perhaps one is not quite “alive.”
Edit: This is not a judgment on those who struggle with this problem! (The thread topic!) It’s a philosophical concern of mine, about modern culture. It seems to me that the difficulty extracting oneself from porn can only be explained by the level of temptation and accessibility to that temptation which is a uniquely contemporary problem.
