Anal Bleeding

So I hooked up with my fwb last night and he accidentally put it in my ass. It hurt so bad I made him take it out right away and I had to like rest a minute because I still had pain from it. The pain eventually went away and we continued vaginally. Today I have some pain in my asshole and then I noticed there is blood marks on my underwear and when I went to the bathroom and wiped there’s bright red blood. Any advice?
