Do I Only Like the Attention

So there was this guy who fingered me in my friend Alex's truck while Alex was driving and we talked for two days after it happened and it was fun talking to him but then every time I tried making plans with him he'd cancel last minute. Okayyy so I gave up but then recently he hmu and we started talking again. He invited me over to his house and I was stressing but then I saw his guy friends and chilled out... so we smoked a couple blunts and he took me to his brothers room cause the guys were all in his room... so we started to fuck and I was uncomfortable cause I was a virgin and I told him idk if I wanted to cause ya know he was experienced and I wasn't. So we fuck and after we cuddled... so the next day I messaged him and he hasn't been responding so I feel like he's been using me and when I told my friend she told me that I only liked him cause he was some hot guy giving me attention and Idek if she's right. So it's like did I make a mistake, was I just used, should I try to talk to him again???
