Accidental "Anal"

So last night my boyfriend and I were having sex, it was amazing he was going fast and I was loving it...until he accidentally pulled out to far and put it partially in my ass. It hurt so fucking much. It bent his dick I half, he said. He was so apologetic and kept asking if I was okay. We contiued having sex once the pain went away. After we finished, I went to go clean myself up and as I wiped I noticed that there was blood. It wasn't bad bad, it was like when you wipe and you realize your spotting type blood. Well today so far there is no blood, but my asshole hurts. Does anyone know how long it will be sore? I'm sorry I know this is TMI but I don't have anyone else to ask. Please and Thank You!
