Questioning my sexuality?

Me and my bestfriend hooked up the other night when we were waisted. I really liked it. I couldn't ever do it with her when I'm sober though cuz she's my bestfriend but I'm not sure about other girls. I've had girl crushes before and I think they're hot but they don't turn me on as much as guys do or give me as much of an emotional connection as guys do. I wish they did though cuz guys are just heartbreakers. So do you think I could be bi?
