Dry spells are very difficult to communicate because it sounds like he truly doesn’t want to make you feel bad.. based on what you wrote I think you should have a serious convo about initiation and set boundaries (I know I get frustrated when it’s like 12am on a work night lmao). I actually like the idea of planning it on occasion, but not labeling it as that, more of a date night, netflix night, etc. You could honestly do that without him knowing but more along the lines of mentally prepping yourself if it does happen? Like plan a night with him watching some holiday movies or something, and see where it goes (as long as he is okay with it of course!!)
