Is there a way to tell?

So I’ve had 2 girlfriends and one boyfriend. I consider myself as bisexual. But the boyfriend I had lasted for barely 7 hours. And I didn’t like him. So personally I think I’m either a lesbian or a bisexual. Is there a way to tell or do you just need to give it a way of Time?
