Kissing advice

(I didn't know what category to put this in) I've been dating this kid for two years, and he hasn't kissed me. He's already had his first kiss, but I haven't had mine. I get teased constantly about the fact that I'm almost fifteen and still haven't had a first kiss. It's honestly starting to piss me off. I've talked to him about it, but this is all he's said. I'm not going to break up with him over something stupid like this so please don't suggest that, but what the hell do I do?
