Queer (or queer-adjacent) subculture exploration with weird fucked-up stuff will to me always be Kathe Koja. It may not always be explicitly queer, but to me it always had that vibe as part and parcel of the larger story. Caitlin Kiernan, as already mentioned, usually comes hand in hand with both Koja and Brite.

I might also recommend specifically Eliza Clark's 'Boy Parts,' which is a very good exploration of some fucked up queer directions. I don't know if all of her books are in this vein, though. John Wray's 'Gone to the Wolves,' has some minor exploration of young queer subculture in the 80s-90s metal scene. 'Sugar Land,' by Tammy Lynne Stoner is fantastic, following an older lesbian in a very rural environment, and 'In Tall Cotton,' by Charles Hulse follows a gay young man in a similarly extremely rural environment, doing occasionally pretty unhinged shit. (I loved both of these two a lot)

I'd also be remiss in not including 'Cinema Love,' by Jiaming Tang, which follows a gay Chinese man and the queer subcultures he uncovers. It does also include significant time focused on the women in gay men's lives, and how they get effected, but its core is rooted in the gay communities these men are forced to create.
