Bi-Curiousity.......?

I'm a girl, sixteen years old. For the past few months, or maybe even longer than a year, I have been wondering if I like girls a little. I have come to the conclusion that I'm probably just bi-curious, since I have never had a crush on a girl and am not really physically attracted to girls. I at least don't see and other things in a ual way most of the time, unless I think about being with a girl. But I do think about girls quite often, and I can picture myself in a relationship with a girl. So I'm kind of confused. Has anyone here felt similar? What conclusion did you come to?
