Source of today's panic attack

Me and this guy were going at it. And it was great, till it wasnt. He got really rough and I tried to stop it but I guess he thought that meant I wanted him to keep going. I never said anything, just kinda froze. When it was over he asked me" this is what you wanted right?" I still didn't say anything. Idk what he thinks. I've showered like 6 times and I keep crying about it but Idk why because everything was fine. I would have said something if it wasn't right? This shouldn't bother me this much. I tried to talk to my best friend about it but we just ended up arguing. Why do I keep fucking thing up?
