I feel a little violated

So to cut a long story short, I was at a work night out over Xmas and ended up kissing a colleague. I got blackout drunk and don't remember much of the night. I have a small memory of going upstairs to my hotel room with the guy and us kissing some more and I thought that was it but he told a guy friend, who in turn told me, that he had played with boobs and even sucked on them. I don't have any memory of this at all and was surprised when I heard about it. I know had I been sober I would've given consent and probably did in whatever state I was in but I still feel very weird and violated about the situation and that I can't remember it. Am I being overly sensitive? I'm not really sure how to feel, it's odd that someone has seen an intimate part of my body and I don't remember 🤔
