Advice please !

Ok so I met this guy recently I'm 20 he's 23 and we seem cool together but the first night we hang out he tried to "Netflix and Chill" but I was on my period so I guess he was upset or whatever even though he said it was ok then tonight we did end up having sex and I'm getting mixed signals he was on top and kept looking away when I opened my eyes but as I was on top he kept his eyes on me. Is he not attracted to me like that? Then as soon as it was over he played his game then took me home without even asking me was I hungry😒. I'm not the type to have sex early in dating but I was so tempted anyways  Should we get to know each other more or what? What y'all think?
