Is it normal that my crush kissed me

So I’ve been having a crush on this boy for a while. He’s really smart, funny, and my type. My friends tell me it’s obvious he likes me but I doubt it. Until today. We were walking home and his hands were around my waist. Then he started playing around with me and asked me to show him a dance move from dance class. (It is cold outside at the moment) I refused and told him its too cold and he said , “I’m not leaving till you teach me something”. So I taught him a basic turn in first position and he looked so funny doing it. Then he started “ballroom” dancing and with me. Next thing you know he stops and kisses me. The kiss was soo good. It got deeper by the minute. I started feeling a lot of butterflies and I was getting aroused quickly. I’m getting so horny just writing this. I just want to kiss him again. His lips were so soft, it was obvious he knew what he’s doing. But he claims I’m his first kiss. Now I can’t stop thinking about this. Is it normal that my crush kissed me out of the blue and may ACTUALLY like me? I’m not really used to this...
