Blackout : did i have sex with a stranger ?

So I 18F went out to the bar i had pregamed half a bottle of wine. Drank 3 shots and then talked to some guys. One of them 30M brought me like 1 or 2 drinks and then i remember going out from the bar with him. But after that total blackout. NO MEMORY. I wake up the next morning in his bed spooning. I am fully dressed and he is in boxers. I do not recall going to his place. I have a few dizzy flashbacks feeling ill on the street. My friend told me I threw up and was really gone. She told me she took the uber with his friends and i took another uber with him just after them. I guess I didn’t have sex with him as I threw up and was an absolute mess. But waking up in his bed with no memory was a bit strange. My pants, panties and shoes were still on so I probably didn’t sleep with him but still the fact that I do NOT recall anything from leaving the bar at 12PM and waking up the next day at 8AM is worrying me. I know I should drink less but I have been drinking a lot a few times and i always remember stuff even if it’s only brief flashbacks. I’m sorry if I’m being paranoid but I’m having severe anxiety rn. And he texted me some days after some gross stuff like asking for nudes and telling me he is horny. But the little i remember we weren’t really flirting when we talked, we barely spoke at the bar.
