Did I hurt his ego and what shoud I do?

Anonymous
I met one guy in pub and we flirted and everything was going great, we really had great chemistry until we were leaving and he tried to kiss me but I told him to stop (because I was nervous and I panicked because I never kissed anyone before - I didn't mention that to him), so he asked me can he at least kiss me on the cheeck and I let him. Next day I responded to his message that he sent me before the kiss happened and he still didn't respond to me. It's been 2 days.
