I need help with my sexuality.

I find myself questioning my sexuality a lot. I really need help deciding. I know you're born that way so will someone tell me please. I find myself looking at girls and finding the attractive I really am interested in fucking a girl, like damn I wanna do that so bad. But when it comes to guys I find them attractive too but girls damn. It's just, fuck I don't know. Can someone convince me or explain please. I'll talk to anyone. Also when I masturbate I find myself doing it to lesbian porn, cuz its fucking hot. So someone please tell me what you think
