You may be a bisexual, if you are sexually attracted to people of both biological sexes (gender identity is not relevant here).
You cannot be either a woman or a feminist unless you are using a completely different definition of both these words to the definitions most people are using.
If you are (a) a woman, and (b) a feminist, what words do we now have for (a) all adult humans of the female biological sex, and (b) the social justice movement dedicated to equality and liberation for the female biological sex?
Neither of these things include you because you are not female and not interested in the rights of female people. In fact, as demonstrated multiple times, you believe what you and other male people want is more important than the rights of female people.
By redefining these words to include yourself, i.e. someone who is the opposite of these things, you are denying the original groups words for themselves, which is an act of oppression.
You are not a woman, you are an oppressor of women. And you are not a feminist, because you believe male people take priority over female people.
