Do I Really Know What I Want?

I'm a 15 year old female with a girlfriend of nine months. She's two years older than me and I'm truly happy with her. Yes, we argue a lot and she's "out" to her parents as gay. I am not out to my parents. I'm not sure what I am yet. I always have the question "Is this a one time thing?" stuck in my head. I like (dare I say love) her so much and yes, we have had sex. But I have never been attracted to any other girls before. I've dated guys, but I always find myself not feeling right with them. I have had innapropriate experiences with males before, when I was eight. It happened and I've gotten over it. But could that be a factor in why I feel uncomfortable with men? I like her a lot, I don't look at other women. I am attracted, but scared of, men. So that's it. My friends and a few cousins and an aunt know I'm gay. My mother has an inkling. And neither of our parents know we're together. I simply want to figure myself out. I have not yet labeled myself. But I want to tell my parents we're dating. But I don't know if I should tell them if I'm gay, bisexual, curious, or straight with a one-time fling?
