Backout drunk + a boy

Okay so I’ve never spoken to anybody about this and i figured if I post this anonymously it’ll be fine. So a few months ago I was at a party and got extremely drunk to the point where I can’t even remember what happed towards the end of the night. However I remember making out with this boy that I wasn’t too happy about making out with and my friends who were there said that he took me away into another room. The thing that scares me the most is that I have no recollection of what happened after that and he said he was too drunk to remember as well although that could easily be bullshit. I don’t know what to think and it’s been eating at me ever since. I’m glad to have got it out and o don’t expect any advice or anything but thank you for listening
