Jaw stress. I actually love gags and such, but my dentist doesn't
This one comes up more IRL when I play in dungeons, but I have a soft limit around being near needle play scenes. That is definantly a me issue, as I can't tell people not to play in a way that is allowed by dungeon rules, but I have absolutely ended scenes because I didn't like what was going on next to me.
I also had a limit for a while of not going into a specific room at a specific dungeon due to a bad experience there. I'm using the past tense here only because I don't go to that dungeon at all anymore.
