awkwardness and kissing

I'm 15 and my boyfriend is 16, we've both never had our first kiss because basically he's liked me for three years but never asked me out because we didn't see each other that often since we were at different schools. so he finally asked me out and we're together now. Okay well we're both like super awkward and it works for when we talk, but I can't really talk to him without making sarcastic comments. he's fine with it, but he's seriously the sweetest guy ever and I want to be able to tell him how I feel and not be awkward about it. anyways, I feel like we're never gonna end up kissing or anything because we're both so freaking awkward about stuff. :(
