figuring my shit out lol

i’m a sophomore and i have a really good friend who is a senior. the other night she said she wanted to tell me something that she’d never even told her best friend. she told me that she thinks she could be bi. crazy thing is, i’ve been super bicurious for awhile and i told her that and it was really nice to not only tell someone, but to have another girl who’s had straight experiences her whole life have the same feelings that i do. if anyone got this far in my story though, how did you figure out your sexuality?
