How to know if you’re bisexual or lesbian???

I do think I'm attracted to both genders. But my attraction to men is completely physical. Like, I think they're attractive, but I could never be in a relationship with one. Is it ok to call myself a lesbian when I still have attraction to men? Or am I still bisexual? I really don't want to use the lesbian label if I can still be attracted to men, but I feel like bisexual just isn't the label for me. Because I feel like lesbian does describe me, but I still find men attractive. I will never be with a man, so is it ok to call myself lesbian? Is there a specific term for people who are bisexual but only date women??? Help.
