Bounty is M50 for a good recommendation, M100+ if I really like it.
"Medium-to-long" means anything normal-novel-length or higher, and longer is better.
Things I like (and will thus make me more likely to enjoy the recommendation):
Time loops
Trans stories (either very clearly thematically trans, or with trans focal characters)
Gay
Science fiction
Fantasy that's written like science fiction
Rationalist fiction
Oh, I like furries- I read actually very little furry stuff, so that might actually be a very likely place to find something easily
I like basically everything on https://recordcrash.com/list/main, so none of the recs on that site count, but it's a good list to get a stronger idea of what I like.
I am very likely to give M100 or more for a recommendation with the first 3 things on that list, and one or more of the next 3. I do, however, enjoy things with few-to-none of the things on that list, it's just less likely.
Webfiction or traditional fiction are both fine, as are fanfics but I'm less likely to pick them (if it's not a fandom I already read fanfic for, I will have a harder time "getting into" the story). Comics, movies, etc. do not apply.
I'm gonna also restrict this to relatively non-horny works. For the moment, I'm good in that respect. A little bit is fine- I actually hate it when stories avoid sex too heavily, but I don't need anything as-or-more intentionally-horny than, say, planecrash.
