He hurt me and i let him

Last night i was super drunk off of 4 shots of johnnie walker but I still remember everything ... i get to the halloween party which has already been shut down an hour into it im drunk and im trying to find my friends who are going around the dorms looking different party ... this guy says he trying to “help” me ...and me being the non-confrontational person i am allowed him ... i honestly think he has a weird fetish that he was living out because i told him i needed to go to the bathroom and he closes the door being the both of us ... i told him to turn the light off because its too bright and he stood there and watched me pee ... afterwards he didnt even let me wash my hands i pull my costume back up and he stands me up and then gropes me all over mind you im 4’11” and hes 6’5 and twice my weight so even if i wanted to do anything i couldnt he sat me on his lap and started to kiss me i didnt want to kiss him back but i let him do it and idk why... he told me he was taking me to his room and once we got there i plopped myself onto his bed and he began to grab and rub at my vagina ... and i let him i didnt want it but i let him i told him to ket me rest but he ignored me and began to harshly grope and put his face all over my pussy and ass he was hurting my vagina by trying to finger me... he pulled me close to him in a spooning position so he could grind on me and sniff my hair i was so hurt... i was trying to get him to get him to agree to do other things so i could get out if there like finding another party or finding me more alcohol i was too drunk to walk properly especially in heels which for some reason i didnt think to take off we only left his room when my friends started calling me on my phone asking where i was i felt violated ...
