I “platonically cuddled” and boy who “jokingly flirts with me” and I can’t stop thinking about it

it’s strange. I don’t have feelings for him. at least not any commitable ones. I jokingly flirt with one of my friends because we’re both straight girls and it’s all jokes and he always wants me to flirt with him too so I said “bet” and I have been. so we’ve been basically dirty talking a whole bunch and making everything innuendos. so lots of flirting. but then the other night, last night actually, we were at the beach with some friends, and it was cold, so we were all kinda huddled together. my other friend, who is in a relationship but really touchy with this guy, was like leaning on him, and I was like “I wanna get in on this cuddling” meaning with her. but then he switched to the middle and had his arm around me and I was pretty much laying in his lap. he kinda held my face and was scratching my head and stuff. he kept laying his lead on mine. it was nice because I haven’t been like that with someone since my last relationship. but now I’m thinking about it. it was nice.
