Caught feels already

So I met this guy at a party like a month ago, we had each other on Instagram and Snapchat but never really talked. Even though I always thought he was pretty cute. But last night we saw each other again at a party and we ended up hooking up after. It was possibly the best sex I’ve had like amazinggg, but I don’t know if he wants anything serious and we don’t know each other that well. He was just really sweet and not pushy and he put his jacket around me, I’m just afraid of how he’s gonna act next time we see each other. I’m worried I’m gonna be let down bc I already caught feels way too soon. Advice?
