AIO for blocking a guy who hurt me

I met this guy on Tinder in December and went on one date previously, we also talked a few times in the phone. A few weeks ago we met up and got dinner, after I went in to their house to hang out a little more. I told them that I didn't want to have sex that night and asked if we could just kiss and cuddle a little.

They end up taking off their clothes and we started having sex anyways, I was into them so I let it happen. Mid way through they start choking me so hard I couldn't breathe, without asking, they realized I was trying to get them to stop and stopped chocking but kept going.

The next morning I woke up with a lot of pain and noticed bruising on my neck. I thought it would pass the next day but it was worse. I couldn't turn my neck and it was hard to eat, or even sleep. I kept crying at work so I brought it up to them.

I called on my lunch break (I work from home) and let them know I was in pain and that I didn't think they meant to hurt me, and was just looking for reassurance and to let them know I was hurting. They said "sorry I guess not everyone Is into it and maybe we went too fast"

It felt like they were brushing me off and dismissing the pain I was in so I told them I had to go back to work. I then texted them and let them know how I felt, I was defensive and think I was acting out of fear and past trauma. But they also didn't ask if I was okay, or give reassurance that they will be careful on the future.

I ended up blocking them, my neck hurt for 5 days and I was scared that it did more damage than I had thought. But the way they responded makes me think I was overreacting. My head also help banging against the wall, and they were kissing my neck so maybe I thought they choked me harder than they actually did and my neck hurt from hitting the wall a bunch.

I felt like reaching out to apologize but I couldn't think of why I would be apologizing, I feel bad for blocking them suddenly, AIO?
