@scorpio-94,
I think time will tell.
At this point in your life, you're apparently not actually involved in a relationship, and you're not sexually active yet. You experience sexual fantasies, and you've had secret crushes, which are also a type of fantasy. You're exploring the possibilities of sexual activity, with both males and females, in your mind. And that's fine at your age.
When you have more dating and relationship experience, and when you begin engaging in actual sexual experiences with a partner, your preferences might become clearer to you.
The important thing is that you seem to have a healthy self-acceptance of your sexual orientation, regardless of what it turns out to be.
