Clean down there..?

So recently I hooked up with a guy and it was really dark. He ended up accidentally starting to stick it in my ass, but stopped when I told him it was the wrong hole lol, anyways he ended up continuing with vaginal sex after that, but I ended up feeling a lot of pain and had a some bleeding from my ass. However my main concern is the fact that he proceeded to continue with vaginal after having contact with the anal area and was wondering if there was anything I could do to clean in there to ensure that I don’t get an infection or anything else. I also don’t know what to do if I do in fact have an anal fission or if there’s anything I can do for that.
