I honestly completely forgot i had a retrosping and havent checked it god im so so so sorry for whoever asked this.
Honestly anything that isn't underage sex or incest, "unsanitary" kinks (like piss/vomit/etc) or excessive gore/torture. For prompts it depends on my familiarity with the subject matter, and if it's a fandom I'm familiar with, or an OC you want me to expand/extrapolate off of, no prompt is fine. Otherwise, it depends on what you're looking for specifically: what ship/character, what part of their characterization you want me to focus on, even themes or motifs or metaphors you want me to touch upon.
Though honestly idk if I'd be able to write anything rn I think I was too hasty opening up comms to begin with
