This is an awesome idea, hotdogfriendo!
One of my partner's favorite pieces of fiction is
Song of Achilles by Madeline Miller, which is a reimagining (and a better one, in my opinion) of the story of the ancient Greek soldiers Achilles and Patroclus.
If you're going the graphic novels route,
Queer: A Graphic History from Icon Books is a good one (although probably more like an illustration of what you've been reading already).
Fun Home by Alison Bechdel is essential queer reading for sure, although it has some pretty dark themes in it, so it's good to know that going in. Also, all of the ones on
this list!
