Advice on after sex

So me and this guy been talking for a year..and today we finally chilled and had sex after that whole entire year. He’s seen me a few times in person but never really looked at me so I was really shy on him seeing me in person I’m not ugly but I’m not as pretty as I look on social media because well you know “filter”. Everyone I know says I look the same but I am thick I’m not a big girl but I’m chubby and he knew that..and I’m 23 and he’s 28 anyways today we hung out I feel like I acted so shy and like so awkward in messages I tell him all the things I’m going to do but I get frozen in person to where I’m shy and I mean the sex was good he finished in less than ten minutes But I felt no connection maybe it was the first time chilling and we should wait for that connection but he’s so cute I guess what I’m asking is I want to text him first but he didn’t even kiss me bye before he left he just gave me a hug and said “ write me” and that’s it really. I don’t know should I wait for him to write me that way I know if he was feeling me or not ?
