I'm confused about my sexuality... I watched lesbian porn, did it turn me into a lesbian?

Watching lesbian porn won't turn you into a lesbian; though it may increase your libido to try it out. If you have never had a crush on a boy and your over 12 years old: How is your relationship with your father? If you have a good relationship with your dad, and you haven't liked any boys ever, it is possible that you are a lesbian. But your still young, there's no rush to figure these things out. Best of luck.
