How would you handle this?

So a couple nights ago me and my boyfriend decided let’s do some new sex positions. To have some fun. So we did those and thn he asked if he could try anal and I told yeah sure but when I say stop u gotta stop because I’ve heard it hurts a little. So he said okay i will. So he had some trouble at first figuring it out. But after a lil he got it. With my face facing down and him telling me to spread my butt. I started to feel very uncomfortable with what was going on but this made him happy so I kept going along with it. He started to get into it more which meant he started to push his penis in me more and faster. I told him to stop because it was starting to hurt. So he did and just put it in my V. And not even like 5 strokes In he puts his penis back into my butt. I kept saying it hurt but he just kept telling its ok baby relax it’s cause ur not use to it. So I just laid there still feeling uncomfortable. It’s like he wasn’t even hearing me say stop anymore. I started to feel my eyes tearing up because it was hurting. He kept putting back in my V when I said it hurt and thn putting back into my butt a couple strokes after.

I love my boyfriend and I said YES to trying anal but idk how to feel. Afterwards when he finished I just laid there kind of in shock like I didn’t know what to say. I felt kind of paralyzed. He kept telling he was sorry for making feel uncomfortable.

Any suggestions on what I should do?
