I can recommend you some novels!
Kiss it better by @DogshitJay is really good if you like a more conventional BL story. (That's my opinion anyway, there's some unique aspects about it and a really fun read.)
The stains beneath or skin by @sxxaint is super unique and atmospheric. However it deals with some heavy topics and can be very bleak, so if you can stomach that, definitely recommend!
I also recommend the series stupidly beautiful, but that's technically polygamy and the bxbxg storyline online starts in volume 2. I love love love the Characters in this one and it's beautifully written.
I only recommend all of these if you're 18+ Though! They all include nsfw content
