I'm pretty sure i'm lesbian, or at least bisexual but i've never been with a girl, let alone a boy. I'm a older teenager but i haven't really met anyone i want to have a relationship with, and those i have, didn't turn out because i seclude myself from others. I don't want people to know that i'm a girl who likes other girls.
My question is, can someone know that they're gay if they haven't been with anyone?
