As you are discovering, sexuality is a spectrum. For many people, it's more complicated than just gay, straight or bi.
You're in a place right now where you are physically attracted to girls but emotionally attracted to guys. It happens. Is it confusing? Absolutely, but it happens.
My advice is to not rush to categorize yourself as something. Take it day by day and don't try to force an answer. If there's a girl that you're interested in, ask her out. If there's a guy you're interested in, ask him out. Just be honest with yourself and do what you can to figure out what you want to do.
Again, no rush. Take your time and do what's right for you. Sexuality has a lot of twists and turns. But you'll figure it out.
