Is he still interested or no??

A guy and I met up and flirted for couple hours. The spark feels right - we had sex. I'm not against having sex on first date and he was very sweet. He fell asleep while cuddling with me (he said he is looking for a girl who likes to cuddle) and behaved like a BF when we went back out. He held me and kissed me while there were others in an elevator. Tbh I was surprised by that.
