Boyfriend only makes out with me?

Call me crazy, but I'm not a big fan of making out because I have anxiety related to feeling trapped and for some reason making out makes me feel suffocated/trapped. I'm 17 and my boyfriend is 16. I was his first kiss so I don't really blame him, but the only kind of kissing we ever do is making out and it makes me anxious. I love kissing, just not full on making out. I want to say/do something today, what can I do? I definitely don't want to be rude or hurtful.
