Wrong hole! It hurts 😭 help

Me and my boyfriend was doing a quickie before we left the house for the movies. And we were both just into it. He picked my hips up and basically half of my body was in the air and he was just thrusting in me. It felt so good tho but just as he was doing that. He RAMMED His dick in my ass. Most likely just the tip but he was going fast. I immediately pushed back and started crying 😭😂 it sounds funny but it hurts so bad. This was the second time it happened but it was long while ago. I bled a little but it hurts to sit unless there is cushion, it hurts when I laugh or couch. It hurts to kinda fart. It also felt like I have to poop right away when it happened. He felt so bad he almost cried :( but what can I do to ease the pain because my anus feels dry or it just stings and it hurts when I clench it. What can I put on it?
