Ok, so I had my first kiss today :-s?

I've only been with my boyfriend for a week....less actually, but we kissed today. I was frickin NERVOUS but he was really cute about it. Anyways, its really WEIRD i didn't expect it to be like it was.....and as CRAZY as I am about my boyfriend....the kissing bit is...iffy. Is it normal to feel like this? Does anyone have any tips for me? Thanks
