Should I kiss him?

met this guy Monday and we have been texting all the time since. We hung out earlier today (ate chilis then went to a lake and popped fireworks). And I had fun, he is funny, kind, and chill, and intellectual. Im a senior in high school but in 3 days he is leaving to another city for college. He asked me if he could kiss me the next time he sees me. But im not sure. I feel like he is using me for amusement. I mean why would he like a younger girl , and especially days before he will most likely never see her again?
