Guy problems

Chelsea
So I've been seeing this guy and he recently gave me my first kiss. I wasn't sure if I liked it (or even kissing in general) because it felt awkward and weird, but I thought maybe I was just really nervous and I should give it another try. The next time we hung out we kissed again and I still felt nervous. My question is am I supposed to feel something when we kiss? Like something physically or mentally? Not to sound like a movie or something, but I'm trying to figure out if I really like this guy or not. So do any of you feel "sparks" when you kiss your SO?
