I don’t know if my sexual assault would stand up with police/court

I went on a date with this man, and it was fine for the most part. I will say he kept buying me shots and got me drunk, and I went home with him (I did consent to this). We ended up having sex and through it he kept asking to do anal during sex and I said no and he kept asking to which I kept saying no. When he was about to cum, he asked where he should cum and I said NOT in me to which he pulled out and shoved it in my ass and I’m like I FUCKING TOLD YOU NO and he just said “oh I misheard”.

I just don’t know what to do and if there is anything legally I can do.
