My advice would be not to concern yourself with labels right now. Yes, they can make such a complex and confusing thing as sexuality seem less overwhelming, but it's so complicated that sometimes it's best just to become more familiar with what you're attracted to and figure out what you identify as later.
For example, I'm almost 21 and it's taken me about 7 years or so to understand where I would be placed on the sexuality spectrum. I experience sexual attraction to both men and women, however I am only romantically attracted to my own sex (female) and my attraction to women is very strong while I've only been interested in two guys over the course of my entire life.
Due to my own morals, I don't become intimately involved with anyone that I am not both physically and romantically interested in and I only see myself ever being in a relationship with a woman. So, because the romantic connection with a man isn't something that I feel, I don't even ever see myself sleeping with a man. For me, the question often was "Well, should I label myself as a lesbian because I will only ever be in relationships with women and I won't sleep with men?"
Some would answer yes to that question, yet I still identify as a homo-romantic bisexual who is more of a "gray-sexual" when it comes to the opposite sex, and I identify this way because I'm comfortable with it and I think it best describes how I feel.
Anyway, my point is that you may not fit the specifics of one particular label, so just focus on what you're feeling rather than what you are on the sexuality spectrum. Things are bound to get complicated.
