Physical and Emotional Attraction

Hey ladies! I need some help. 
For the past 4 months I have been seeing this guy, we hang out all the time. He's sweet, respectful, funny, slightly awkward and a complete nerd. He's basically me but with testosterone. I have the emotional attachment buuuuut, when he kisses me... I feel nothing, zilch, nada. So I thought if I made the first move I'd feel the spark. I kissed him... and still no spark. I don't know what to do. We have a great time together but is the physical attraction just as important as the emotional?
