ohhhhhh i could ramble about this for pages and pages! hard question! (sorry this took a while to answer!! i ended up cutting a lot because it was way too much and now i'm happy with it ^^)
my tastes are VERY broad... usually it's "i know if i like it when i see it", but here we go!
likes
- some themes i like
- weird body shapes like taurs, wyverns, etc
- getting covered in goo/paint/mud/rubber
- pooltoys/plushies
- blushing at actually enjoying it
- losing speech, only barks or roars now
- like when a sona turns into a different species with their same markings/design
- i like both willing and unwilling TF
- and i like both permanent and temporary TFs too :3
dislikes
- i don't like complete mental changes (loss of identity/memory)
- basically if you TF someone into a dog and fully turn their mind into a dog, and make them forget their former human life.... you've just created a dog.... when there's no former human in there to enjoy it, what's the point!
i think in general what i like about TFs is not the TF itself but the aspect of "being formerly a human and now living as an animal". it should come as no surprise i'm a huge fan of extended post-TF comics/stories more than extended sequences :3
