Yeah, my first kiss wasn't anything special either. I felt nothing during nor after, besides the fact that it did feel a little weird (all the saliva making that odd sound freaked me out a little). Perhaps I was doing it wrong, I dunno, but I kept it short just in case. Anyways, it's a yes to both your questions; it's normal, and it's because you're not used to it. Also, just take it slow, don't try to do too much, or you're bound to really fuck something up. Nothing wrong with doing more, just wait until you feel you're both ready. And remember, communication is key.
