Am i Bi-Curious?

There is this girl at my school and she's bi. She likes me but shes dating another girl in the other class. at first i hesitated if i liked her or not but then it became clear i didnt like her and it was just my hormones because before she started dating, she would hug me and do things to me in which what couples would do so she had a thing for me. i guess it just wasnt normal for me because im always so used to a guy doing that and not a girl. anyways, i dont have any romantic feelings towards her at all nor do i get jealous when she is around her girlfriend.I have a boyfriend myself and so i dont feel anything towards her. but there were a few times where me and her almost kissed and i kept thinking "What if we did kiss?" and since then i've been having thoughts about her and wondering what it would be like to kiss a girl and makeout with one. i remember going into the bathroom only to find her making out with her girlfriend, and after seeing that i've wondered "i would like to do that too.." so.. am i bi-curious? or bi? because i HAVE dated a girl before, but that was online and i wanted to experiment.. I also have NEVER done anything with a girl before either..
