I have no idea what my sexual orientation is?

You can try to analyze your feelings and sensations about boys and girls. You can try to imagine yourself with different people in sexual and romantic contexts and be honest with yourself about how that makes you feel. Your emotional and physical responses to these fantasies will give you a hint of your orientation.

That's completely ok! Sexual orientation is a very subjective thing, and usually takes time to figure out. It is worth keeping in mind that you should never feel pressure to identify with any label if you are not ready. Age, experiences and interactions will shape who you are, and sexual orientation is no different. When I first started questioning my sexuality I went with the term 'not-straight' to start. I didn't feel comfortable with any other ones, and I wanted to figure out what each label meant to me personally, and how it would represent who I was and how I felt. I can't make you choose, but what I would say is to have patience, and you will find what fits eventually
