Just go with life right now, it'll click when you least expect it because your mind will deceive you more than often over what your heart says. You also have some years before everything starts sticking to continue your path.
For the longest time I always thought I was completely straight and I wasn't wrong for the most part, I can still admire a woman and her beauty but I for the most part might as well be bi especially since the person I am dating right now...well not too important, just that they're a man. But to say the least when he asked me I was still on the "I AM A MAYUN. SPARTA, WOMEN, SLAYING DRAGONS!" mindest so, spoiler, I initially said no though I did notice I was flattered and other things which is when it clicked for me. Now I am in probably the happiest relationship I could ask for.
But yeah, like me and others are saying, don't worry about it and just go with what your heart says, no point in letting your mind tell you because when you do figure it out it will be out of nowhere most likely.
