What is something your partner wanted to try during sex that made you nope out?

My ex liked to be bitten during blowjobs. I lost my virginity to him and was super inexperienced, so this terrified me. Not just pressure, not a light scrape. He wanted me to bite down hard to inflict pain, like if I was biting into a steak. Did it once, was too afraid to hospitalize him or bite his dick off, so I put an end to that.

We had a really nice long-term relationship overall, but I couldn't really get past this. He was just an all-around masochist and it freaked me out because I don't like inflicting pain and he was my first partner ever. He loved to be bitten and scratched anywhere I could do it properly, and once again these weren't love bites. These were 'one muscle twitch away from tearing a chunk off' bites. The scratches bled. He started calling me Mistress out of the blue. The sex on it's own was vanilla. Just beforehand he really liked me to fuck his shit up.

Turns out nowadays, I'm into casual BDSM as a sub. I now think of that relationship as the little red flag letting me know I was playing on the wrong team.
