I lost my virginity and I have so many mixed emotions

So I was at an afterparty for a dance competition and there’s this nice guy on my team that I’ve talked to occasionally but we’ve never had much chemistry. Well, I got pretty drunk that night and I apparently (I don’t remember) smoked a lot of weed too. According to my friend, me and this guy started talking a lot and I started making moves on him. We eventually left to have sex. I only remember pieces of the night and I don’t think he drank that much. He walked me to the door and I walked by myself to my room doing the complete walk of shame. He never texted me after and I didn’t see him again. I actually had to text him first to tell him I had his clothes. He doesn’t know I was a Virgin so I just assumed this was his typical one night stand. I’m just so shocked and confused because from our team practices, he seemed like such a gentleman. Everyone loves him and he is super sweet and helpful to everyone. I wouldn’t expect this behavior from him. Also, we didn’t use a condom and I’m not on birth control anymore. I gave all my friends so much shit for not using condoms and I am such an advocator of safe sex. I know for a fact that if I was even a little more sober, I would’ve said no to sex without a condom. He didn’t cum inside me luckily but I still took Plan B the next day. It has been such an emotional week and I don’t know if it just the hormones. I wish I could remember enough to know if I was taken advantage of. I waited so long to lose my virginity to someone I loved, and for the past few months I had been okay with losing it something like this. But the fact that I don’t remember how it started and that we didn’t use a condom makes me feel uneasy. I think I had a good time but I definitely would’ve felt better if he had reached out to me after. Now I can’t stop thinking about this, my mind is constantly wandering. I don’t know what to do when I see him next. He’s not even really making an initiative to talk to me.
