Drunk, rebound sex?? Idk. HELP

This is my first time posting on here, and tbh I'm a little nervous. Anyway, I am 17 and I very, very recently just got out of a three year relationship. I've been with this boy since I was 13, and he was 14. I still love him very much, and I probably always will. I consider his family my family. However, we constantly argued and the relationship just got really unhealthy, and I was dealing with personal issues that pushed me into a depression, so I decided to end the on and off relationship for good. NOW, to the topic I'm trying to get at. This past weekend, my friend took me to her friend's house (It was me, her, three boys and another girl) She's 19 so I'm assuming all of the boys were around her age. We started drinking 4 lokos and playing beer pong. It was the most fun I had had in awhile since the breakup. We were all dancing and laughing and just having a good time. But one of the boys who turned out to also be 17, started getting close to me and talking to me. He was super attractive and really sweet. Soon, it was 5 in the morning and I was falling asleep on this kid's shoulder. Earlier in the night we had been making out but honestly, now all I wanted to do was sleep. He asked if I wanted to go lay down, and I nodded yes, so he helped me up and we went and laid on a futon in a back room. Well, we ended up having sex TWICE, without a condom. It was great, don't get me wrong. But all I could think about was how tired and drunk I was, and how I was going to regret this in the morning. I felt like since I had been flirting with him all night and dancing on him and kissing him, and since he had me in bed already, I really felt uncomfortable saying I just wanted to sleep. So I just went with it. Well now, he has been snapchatting me and my friend and I are going to be going camping with that group of friends this weekend. Its his birthday too. I'm scared he's going to expect sex again and I honestly don't want to do that again. I'm not that type of girl, this is the first time I've ever had sex with someone thay I just meant. Ugh help?! Advice?! Does this make me a slut? Just because I had sex with him already , does that mean I should do it again? 😭😭😭
