Drum corps first kiss

Hello! So I’m 18 and haven’t yet had my first kiss, which I don’t mind, but there’s someone who I’m interested in that I think I have a pretty good shot with. He’s 17 and we both agreed that we’re attracted to eachother but don’t want to date anyone right now (we wouldn’t work in a relationship anyway, we’re more physically attracted to eachother). We’re bus buddies in drum corps and have had some nice cuddle sessions and some pretty intense “I really wanna kiss you” eye contact, but neither of us have made a move (maybe I’m misjudging the signs?). I’m looking for some tips on what to expect from a first kiss (and how to even do that), what to do if I get rejected (play it off somehow?), and if I should even go for it in the first place. Thanks in advance!
