Here are some fanfictions I like, organized by fandoms and ships.
Please apply the "dont like; don't read" rules here: don't go to a fandom/ship you hate or are uncomfortable with, and don't start reading a fic before checking that the rating, summary and tags fit you. This list includes RPF ships, as well as some explicit fanfictions, and although I did my best to be clear about the content of the stories I recommend, you are ultimately responsible of your experience. Take care and enjoy!
My friend Azaliz has a good fanfic rec page on their website.
