The answer seems pretty clear to me, hon.
The thing about gender, in my experience, is that it's just as much (if not more) about how you feel as what you think. Feelings and emotions are more primal than thoughts. They come from a place before words. Before the concepts used to put them into thoughts. Call it instinct.
From what you've said about how you feel when you see yourself as both genders, the differences between each one. What do your instincts tell you? What feels more intuitively likely? Don't think about it for a second, and just allow yourself to feel the emotions that go with feeling male, or feeling female... and then answer which of those feels more like it can allow you to express your true self.
