Happy Little Vegemite! or not?

Ok, so as u probably already know I have a boyfriend now (who is fantastic by the way). But the thing is we have been out 5 times now and I have not properly kissed him yet. Well we did, but heres how it went: Mark had the flew the first 2 weeks we were seeing each other, so we didn't kiss, then when he finally got rid of the flew and we went to dinner tuesday night, we went up to mount Tamborine after dinner to look down at the lights and up at the stars, from the top of the mountain. Now it was all dark and the stars were out (some clouds). He was holding me in his arms and we were close. I was waiting for him to kiss me and I think he knew I was a little apprehensive (only because I have never kissed anyone on the lips before). I was worried I would stuff it up and kiss really mong. Well, anyway, he came close to my face and I really wanted to kiss him, but I kinda turned my cheek. Then he kissed me on the cheek. We stayed there in each others arms and then again, he leaned close. We pecked on the lips then I turned again. He said it's ok, I don't want to rush you into anything. I said, "no, I just don't want to be bad at anything". Then we kept on hugging and being in each others arms, and then I kinda put my face closer to his and we kinda kissed like 5 times, but I don't really know if it was propper kissing. It was like kissing someone on the cheek, only we were kissing/pecking a few times on the lips. Then I turned my cheek again. So I am so confused cos, it felt like I was mong at kissing. His lips felt nice and it felt like he was doing a good job, but I was so mong. And I don't really know if I was doing it right. This is so bad that at 20, I don't know how to kiss, but I have no idea what I'm doing. Even with all the advice Sabrina has been giving me, I still feel mong. The real question is, do I tell him the truth, that the reason I'm not kissing is not cos I don't want to (because I really really wanna kiss him heaps, all the time), but because I'm not sure how to or if I'm doing it right? Should I tell him? I feel so bad! I think I'm in love with him already, but I can't even kiss him cos I'm scared I'll do it wrong. It really felt like I kissed him mong. I don't know, help! I am so happy because he is so wonderful, charming, cute, smart and funny, and everything I want in a guy, but I'm really sad about me not being able to kiss him properly. It's not cos I'm friget, but more cos I'm scared he will think I'm crap and can't kiss. Help me please!
