There's a twisty thriller with a gay couple as central characters: B&B (2017).

It's scoring slightly above 5 at imdb, but I suspect it is getting downvotes from homophobes, as there is a fair bit of sex (artful, not porny).
It's available now via streaming (and torrents, of course), fine for a weekday night at home.
