Welcome to the boards.
The thing with this stuff is that very few people are going to have a sense of what their orientation is when their sexuality as a whole is so new to them, and they've barely, if at all, begun exploring their sexual feelings about, and any kind of intimate relationships with, other people. Sexuality is a lifelong process for everyone, so big answers are often hard to come by, especially so early in life.
The good news is that no one has to know their orientation so soon -- or at any age, really. It's not like any of us need to check in with the Orientation Certification Committee or anything.
So, where you go from here is that you just see as you go, based on how you feel and what you know about yourself so far. And if you or someone else wants you to name your orientation -- and you want to -- then you use whatever words feel most true for you and you're most comfortable using. And when people are questioning like you are, the term "Questioning," is a term plenty of people use to name their orientation while they're in that process.
