Am I gay for kissing a guy? 🤔

Context: I was very drunk with a few friends and we were chilling at a gay bar in Bristol, because it was the only club open on a weekday. An older guy, double my age, I'm in university in Bristol, started ruffling my hair and flirting with me, he'd been following my group the whole night. Then he leans in and french kisses me and I guess I was too drunk to stop it, so it continued for a minute. I ran away then, my friends had already left. The next morning I woke up hungover and feeling weirded out. I'm not gay, I like women, the kiss felt so wrong and actually disgusting to me (no offense). BTW it was my first kiss with anyone. I feel so messed up and uncomfortable now. Am I overreacting? How do I get past this?
