Anal! *TMI*

So recently i just discovered I might have done anal for the first time but I’m not too sure. Drunk sex had me confused when I woke up the next morning to use the restroom to see a little bit of blood from behind as I wiped along with some pain. I’ve had vaginal sex before and don’t ever have pain until it was from behind this time. Everyone says I did but I don’t remember 😭😭
