quite a few, vore is the one that ive talked about on this account before but im also really into feet and havent written anything about it outside of unfinished drafts
theres also petplay which i really like but havent written about outside of my really old and bad stories
noncon is also something im very into that i havent quite written about outside of my old bad stuff though most of my stories are pretty dubious consent wise even if they dont have sex lol
