I was having similar feelings when I was 17 too, and I wrestled with feeling like maybe I was bisexual, but I didn't like that term, and then I thought about using the term pansexual, but I didn't like that so much either.. and I came to rest on just knowing that I'm queer. If I feel like I really need to find a specific label, I can rethink that, but right now I know that I'm not really boxed into any one way of being, and my relationships with others are less about labels and more about the person who is in front of me and what our mutual experience is- that embodied feeling is more important to me than what I feel like I need to say to explain it to other people. Does that make sense?
