Is it micro cheating, rude, or something else when a partner views endless social media posts of near naked women?

You know what I'm talking about. In some ways I wonder if it's not completely their fault. The image will come up, activate that part of the brain that likes it, the app knows you viewed it longer than other posts, and the algorithm says to show them more of it. Then it isn't long until their feed shows more of that category than any other. (The app is Tiktok and others similar to it)
