Hi, I recently went out with my friends to the club and got severely drunk where I don’t remember anything that happened afterwards, I ended up waking up in my room with a guy I had never met before and apparently we did it and mind you I’ve never done it before. So this was my first time with a guy. I’m confused as to whether it was consensual or not because afterwards he gave me some stuff he was using (white) which I’ve never tried before either but we went to the pub and coffee cause he wanted to feel awake and I said okay. I can’t remember if I gave him my consent or not cause I was so wasted. Is this considered something else I’m really confused.? Please give advice or anything
