@shipperslist If you are up for gut-wrenching and beautiful, there's TJ Klune's "We Burned So Bright."
Also maybe try things from Freya Marske and T Kingfisher. "The Reanimator's Heart", Kara Jorgensen. Maybe "This is How You Lose the Time War."
"The Man Who Fell In Love With the Moon" by Tom Spanbauer is an absolute smorgasbord of problematic stuff, but another of those gut-wrenchingly beautiful books that stay with you. The MC is a gay man in his 20's, but all the close surrounding characters are older and that really sets the tone, and it's a magical realist semi-fantasy set in 1890s (?) Idaho. CW for all the things.
I've heard good reviews of Amy Rae Durreson's books and that some have older MCs, but I haven't tried her work out yet. Same with K J Charles.
Edit: probably should mention that these swerve towards fantasy-with-romance rather than modern here-and-now romance, just because that is more what I've personally been into. If that's not helpful, then apologies in advance!
