Hi there! I know where you’re coming from. I am a teenage girl in high school, and I’ve always found male genders attractive, until, while still finding male peoples attractive, also fell hopelessly in love with my female best friend. At first I freaked out, worrying about my family’s reaction and how my friends would react.
I told my friends how I was feeling, and they accepted me with open arms. A few months later I told my mom, and she seemed okay with it, and hasn’t brought it up since.
You don’t have to come out to anyone if you don’t feel totally comfortable with doing so. Remember, these kinds of things I take time, and you shouldn’t feel rushed or anything.
If you feel like you’re bisexual, then so be it, because that’s you, and it’s you being yourself.
It’s totally okay to feel any sort of way you feel.
