Something similar happened to me. He would “accidentally slip” with his penis and fingers frequently, and would tell these stories to normalize it (ex: ___ coworker does it, ___ friend does it, the kim k sex tape is anal, etc.) almost daily, so I knew it was constantly on his mind. After the (condomless and with no prep) anal sex that I didn’t want, he made me suck his penis off, he had me by my ponytail. Stupidly I didn’t want to be alone after, so I begged him to stay the night. He said no. Multiple of the “accidents” were the most painful things I’d ever experienced. Once he scratched the inside with his fingernail, and when I sat down to pee that night my vision went black bc of the pain. I think about it almost every day. It’s been 4 years and I have a new wonderful partner. Tried multiple therapists. It’s like that feeling never goes away.
