[I’m a woman] I feel sexual attraction only of people of the same sex as me and I feel a romantic\affective attraction of people of the other sex and also of the same sex, but most of time, women only. Can I still call myself bisexual or am I homosexual?

You’d be monosexual (in this case you’d be homosexual) but you’d also be a biromantic/panromantic depending on which ID works best for you! ^^
With love,
