Nothing is a bigger turnoff for me than...
fat - Char is a slobby, farting mess and/or has weight-related health problems
vore - Char is reduced to a skeleton
inflation - Popping and the threat of it
macro/micro - Blood
anything with text - The words "master", "slut", "bitch", "fuck", there are probably others
anything with audio - Voice acting, sorry to all the pr0n VAs out there
