Try dropping some hints with her. See if she would be into it? No one is 100% straight (my personal opinion), but she might not be into it. That’s fair. But try something before it drives you crazy.
If not her, then you’ll find someone else you like eventually and you can test out the lady loving waters with her. It’s okay to be attracted to a girl. It’s okay to be attracted to a guy. It’s okay to be attracted to PEOPLE. 🙂
