Not sure what to do now

Last week I went to a club and got very drunk. I spoke to a guy from my university for a while and I ended up going home with him, the last thing I remember is being sat in his kitchen feeling very drunk. I woke up in the morning with no recollection of what happened after the point when I was in his kitchen, however I was in his bed with no clothes on. I asked what was going on and he said we had sex, I initially didn't believe him because I couldn't remember. I kept saying no we can't have because I would remember something like that, and he said bluntly in response that I had passed out and we had sex. He then said I should get the pill because he came in me. I was so confused and shocked by what he told me, I got dressed and left straight away. I couldn't believe it happened so I didn't report it or tell anyone. In a way I feel like it is my fault as I was so drunk that night, and I don't know whether I should tell anyone of authority i.e police because there's no evidence, I can't remember anything myself, i'm not sure if what he did is even wrong and I am just going off what he has told me. Basically the situation is just really confusing me and I don't know how to feel about it because I don't remember anything, and he lives near me so I feel like I can't escape thinking about it and trying to remember what happened.

Were you previously in a relationship with this guy ?

Had you had sex before ?

There cannot be consent as you were passed out.

Each society views these things differently.I don't know where you are and there is little chance you are in my country. (Australia)

You may need to talk with what passes as a rape crisis centre in your area to understand the implications of doing anything.

Take care, and go easy on yourself.

No I did not know the guy before that night and I had never seen him before. I am from Birmingham in the UK. Thank you for your advice Terry

Yeah talking it through with people who deal with this will give you some options.

Good luck, take care.
