Turned on by a woman.......

Okay so I got turned on by my friend . We where hanging out and we where fighting over my phone (play fighting) we are both petite woman so it wasn’t rough wrestling. And she pinned me down and I just got turned on I’m 22 and I’ve never been sexually attracted to a female before??? I’m very confused right now ?? She’s bi but I identify as straight please just give me advice I’m so so confused
