It can mean you are gender fluid, or just enjoy experimenting with gender! If you feel more comfortable without any labels and just have it being you, that's perfectly fine. The gender binary puts a very strict idea of what male and female is and what is not. And it does complicate things. I found it helpful to read and ask questions when I was first coming to terms with my identity. And even if you're not any of the things listed above, asking questions may even help you understand yourself more.
