Anal sex

Had my first time anal today and probably won’t ever do it again lol. I didn’t really enjoy it too much but anyways my ass feels just weird. Like I feel like I need to poop really bad but the outside feels bruised. I went to try and use the bathroom afterwards and I got nothing but some anal bleeding. I read that is supposed to be normal but is there anything I can do to make it feel better? My whole downstairs is throbbing.
