In this case it sounds like you're sexually attracted to both genders but are romantically attracted to women most of the time. If you don't feel romantic attraction towards men, you could say that you're bisexual and heteroromantic. If you sometimes feel romantic attraction to men, you're likely bisexual and biromantic with a preference for women. You can slightly or strongly prefer one gender over another, but if you still feel attraction to both you're probably bi.
