Shitty sex?

Guy had next to a micropenis and had the nerve to put on a fucking magnum 😅 it was such a turn off and I’m disappointed because he wasn’t even attractive looking back. It was like 4 pumps and done literally the worst sex ever. He couldn’t even eat my pussy right with instruction(me telling him what to do). It wasn’t even hard I should’ve left. He was kissing with wide eyes and disgustingly sloppy. Then he wanted me to suck his little ass dick?!? Lol I said no. Basically I would’ve been eating his pubes. I wanted to vomit by the end of it. How do I break it to him gently that I can’t live a life of shitty sex? It’s not his fault it’s small but damn. I didn’t say his dick size was a problem by the way it was everything else.

Update: I literally was just sharing my experience. I’m not such an asshole that I would’ve said that to him. I could’ve posted a pic of him. I could’ve been a lot worse. Just saying. If you didn’t like what i had to say you can keep your comment to yourself. If I was body shaming it could’ve been a lot worse. His dick was small is that too brutally honest? Do people want lies told to them? What should I have said?
