Hi there! Everyone defines their sexuality differently, and labelling yourself isn't necessary. Sexuality as a whole is a sliding scale. I know people who identify as queer or LGBTQ in general, and they have days they see themselves as more one gender than another, or attracted to one gender than another.
You don't have to identify or label yourself. If you really want to though, try one label and see how you feel about it a while later. Remember labels aren't final. If you find one you're comfortable with now, but a little down the line you change your mind, you're allowed to! All the best etc.
