Past trauma when he initiates advice

I’ve been seeing this guy exclusively, it was long distance and we finally met. We had a few in person dates which went really well, it’s clear we both have feelings and want to be together.
The thing is we were kissing and things were progressing further but I got triggered, now I’ve had bad experiences in the past where guys wouldn’t listen when I said no and kept going, I kinda got flash backs and I shut down. I hate that this happened because I want to do things with him but I couldn’t as I got so in my head and clearly upset. He did stop when I asked him and respected me, then I briefly told him why I was being that way. I can’t help but think I ruined the whole evening and want reassurance that I didn’t, I don’t want to ask and bring it back to that mood though. I have this fear it’ll make him want to leave (silly I know)
I really thought I had gotten over my trauma, has anyone else gone through something similar? What helped you?
