non-consensual kiss at a party

hi, i'm kinda embarrassed to talk abt this bcs it literally happened a month ago but oh well. i went to a houseparty, got quite drunk and was wearing quite a revealing outfit. i got there and after a while, there was a boy who i was kinda friendly towards. we held each other whilst walking around (i don't remember much, except his friends winking and saying 'well done' but idk bcs i was pretty much gone.) we got to the stairs where a couple of girls and a guy was sitting. i don't remember how the conversation went, but it ended with him grabbing my face and kissing me. i was kinda grossed out that he didn't ask me first, and felt really uncomfortable. i ran upstairs to the bathroom to keep to myself and i met my friend up there. i also remember drunk-babbling 'he kissed me and i really didn't want it'. i had fun at the party but i recently went to another one, and i couldn't stop thinking about his stupid face. i think it's affecting me bcs i shiver or flinch whenever i think abt it, but it's pretty pathetic seeing as he didn't SA me or anything. any opinions?
