What should I do?

What’s should I do if I told my boyfriend about my boundaries on watching explicit videos of other women months ago and he said he won’t do it because he doesn’t want that to cost our relationship (I understand guys are visual creatures but they’re certainly not dogs they’re men and me know how to control themselves at all cost.) but then I saw his history on watching girls half naked and stuff but he doesn’t know I know that I saw it so do I confront him like I did before? mind you it has happened multiple times and I’m so tired of it already.
