coming out

i've been having a really hard time lately figuring out my sexuality so i've decided to go unlabeled. i know im attracted to women, but i dont really know if ive ever been attracted to men. soooo... besides the point, ive been struggling on how i should come out to my parents. im scared that if i cant even figure out my own sexuality, how are they going to accept me if i told them that i like women? my sister especially throws around the f slur as if it were nothing and she constantly bashes me and calls me lesbian for reading yaoi and yuri mangas,,, telling me that i should start reading more 'normal' stuff. i know i dont have to come out to anyone yet, especially since im almost 16, but i just wanted a place where i could get it off of my chest. i really have no one i can currently confide in about this problem... so i figured this was a good place to do it-_-
