Am I being taken advantage of by a dom?

Hello. I think I already know the answer to this, but I also feel like I’m the cause of all these problems. Advice is very much appreciated!

I, 22F, met this “dom”, 55M, on FL. I have a fetish for older men but I feel like it is unhealthy to be engaging with someone thrice my age. It was in a way a spontaneous kinky hookup, and I regret it. I did get to know him before we had sex but I feel like it was unsafe and stupid decision on my behalf. In short, I told him I wanted to use condoms but he, “left them in the car”. I felt pressured as he was grinding against me/almost put his cock inside me so I half-heartedly agreed to raw penetration. He fucked me mostly hard and without a lot of lube, so I ended up getting super inflamed/puffy down there. I told him this and he apologized, saying he “thought that’s the kind of rough sex I wanted”. He also doesn’t seem as informed on kink as I thought he was. He says he’s still exploring it.

I ended up calling our dynamic a quits, which he was very upset about. He still wanted to keep in contact and for some reason I stupidly agreed. He kept flirting with me, and I agreed to meet up again. I felt bad that I ghosted him, so I agreed to giving him another chance at sex. I thought maybe I was just jumping to conclusions, maybe it was a bad/communciation-lacking start. Now I’m sitting here, realizing how much of an idiot I am. I think this guy isn’t good for me, especially due to the age gap. He seems nice and asks for consent, but I don’t feel like that is enough. Am I being taken advantage of, or is this a misunderstanding/improper communication? Thank you.
