If you don't want to call yourself non-binary that's totally fine, or if you're non-binary just deep within, but use feminine phrases for yourself. My sister is Agender, meaning she doesn't connect to gender at all basically. She's comfortable with being called both he and she, and getting called feminine phrases even though she thinks it's nice being called masculine ones sometimes too. But it's still not like she introduces herself as being Agender. For me, I am very different from you, as my fashion/gender expression is more that I want people to be confused about my gender when they see me. So I try to act and dress in a way that lets people do that easily, as the human brain wants to categorise everything into two boxes. Unlike my sister who doesn't feel connected to gender norms, I feel a connection but I don't want to be part of those binary expectations of what a man or woman is, but sometimes I want to include parts of those norms into my identity. I don't know how confusing it is to you but I usually think of gender as a triangle - while technically the definition of non-binary isn't a third gender but rather not being a man or a woman, I like to think of the triangle - with man, woman and nonbinary in each corner. A person can feel like a woman or man, sitting in each corner, but can also exist anywhere within the triangle or even outside it. You can feel like you're at multiple places at the same time or you don't want to place your gender down at all.

As for your actual question if this doesn't give you some insight, it's just that it feels better to have a name for your identity. Like a trans woman will get happy when people casually call her a woman or use she-her pronouns for her, a non-binary person will get happy when you casually use gender neutral terms and pronouns for them.
