Deal-breakers in the bedroom?

There's so many posts on here discussing fetishes and kinks and stuff but I'm honestly curious on what people absolutely WON'T do or is an off-limits thing for them during sex with their partner.
Personally I'll try almost anything besides:
Rape play, piss/scat play, blood/knife play, anal, cuckholding and humiliation (mainly name calling- stuff like calling me a bitch, whore, etc.)
What're the things that you personally find off limits?
