some are sure, some are slightly curious and some are very curious? one thing i am learning in the realm of sexuality/gender there are very few absolutes, most are on a spectrum, either moving on that spectrum or more stationary. go with the flow till you find you.
I think it is possible it could mean you are just confused with your feelings or some different romantic orientation is involved.
Hmmmm..Probably..In my case, i think it was like a transition from being bicurious to having a realization that i'm really into both men and women.
