My FIRST kiss. Is he lying to me when he says he enjoys kissing me?

This guy asked to kiss me after only a few times going out and I agreed. From then on we got a little more serious in PDA. He would tell me he enjoyed kissing with me but he was my first kiss. He didn't know that though. How am I suppose to know if he is telling the truth or just saying that so we'll continue to kiss when we hang out?? Am I actually doing something right??
