Am I into girls?

Hey so I have always said I’m pan because I feel like I would date anyone if I felt like I liked them/could love them. I’m currently in a relationship with a guy, but I’ve been noticing some girls in my fitness classes... I find them attractive but I’m not sure if it’s sexual attraction or appreciation of their beauty. I’ve kissed a girl once, but it was a peck on the lips with a stranger at pride because of a dare. I definitely felt something, but I wasn’t sure if it was attraction or my curiosity getting the best of me. I’ve had girl crushes on and off about every year or so but I’m mainly attracted to guys, or at least that’s what I thought... I’m so confused. What do you all think?
