I've never had a female crush, but I do find some women attractive, usually famous women. Occasionally I think a woman I know is attractive, but I don't want to have any romantic or physical contact with them. With women it's more bodies, with men faces first and then bodies. It can be confusing. But I never see women as potential romantic partners.

It sounds like you're bisexual to me but how you can know if you have never tried both men and women several times you can't be 100% sure. Sexuality isn't that simple. Everyone can find people of the same sex and the opposite sex attractive. It doesn't mean that you're gay or straight. I do think you have to experience it with both genders and you might find a preference that way. It might be obvious to you, I don't know. If you're going by the number of crushes by gender you have had you would probably think you're gay, but it isn't necessarily that simple. As someone said, only you can know, we can't feel what you feel so it won't help asking other people.
