Hello there!! Well Im a teenager myself, and I can easily tell you there is deffinately a part of me thats attracted to girls! I know Im not a lesbian, I could never have a relationship with a girl or anything, but kissing them is just fine with me! hahaha. I have a boyfriend in which I care about more than anything, I wouldnt trade him for the world, but yes....Girls are just attractive people!!
But anywho...back to you! Dont worry sweetie...Its 100% normal! I wouldnt fret too much about it. Just let whatever happens...happen

Take care dearie.
