Just be happy with who and what you are because it really doens't matter if you are gay, straight, bi, trans, a-sexual, whatever, as long as you accept that as your norm it's all fine. You're really young and there will be tons of time and experiences ahead of you and you might change who and what you are a dozen times over before you settle into something really comfortable for you, but again it doesn't matter, time is something you have a lot of, so no need to worry, just carry on carrying on and be happy and confident in yourself.
