I hate hot grease splattering on my skin or clothes but I never cook meat, and these days if I fry anything I avoid making the oil very hot - that gets me out of the risk of splashes, as well as preserving the kitchen walls from getting covered in grease from the condensation (no extractor fan or hood), and it might help to reduce the formation of acrylamide which is supposed to be quite toxic. I miss out on the joys of crispy fried food, which is a shame because I used to like that, but you can't have everything.
I don't like pain generally. I probably hate getting minor wounds more than the average person. The pain distracts me from more pleasant things, and I probably worry too much about minor physical harm. But I don't shake or get anything like tourettes, it just bugs me. With more intense pain and injury, I think I feel that just as much as the average person, though if I hyperfocus on something else I can sometimes screen out the bad sensations for a while.
