Who Am I, Why Am I Here?

I am a girl. I am also a boy. And I am a man. I think of myself as simultaneously the most feminine woman and the manliest man to ever exist. When people talk about gender fluidity, I get it. I identify as female and I don't sway on that point in the least. However, I greatly value my masculinity. And I love that my best friend, Sean, does as well.
It bothers the guys at work so much when I call myself a man. Sometimes I'll stock one aisle before two guys get done stocking another and I'll flex and yell, "I AM THE MANLIEST MAN IN THE WORLD." (We work overnight, when the store is closed.) And Jon or Patrick will say, "You're not a man! You're a girl! You're so not a man at all!" And I'll say, "I'm more of a man than you." Because of this, Patrick likes to poke fun at me and say that I "must wear the pants in the relationship."
That's another strong point of identity, though. Being dominant or submissive. Now I feel like... there is no doubt that I have a very strong will. I can be intimidating. I can be difficult to work with. I'm high maintenance for sure. But I think of relationships as a partnership. I don't assume a dominant or submissive role in a relationship. And I wouldn't want to be in a relationship with someone who felt like they could overrule my opinions or someone who felt like I should run the relationship myself.
I think of myself, first and foremost, as a future mother. I make all of my decisions based on the hope that I will one day raise a family. It's all I really want in life. Yes, I have personal aspirations. I want to be a concept artist. I want a big house with lots of room for me to do my art. I want a husband who loves me. But no matter what job I have or where I live or what kind of house I have or what kind of car I drive, I will always have my family.
Lately I've been trying to come up with a tattoo idea that represents me. And I'm currently playing with the idea of phoenix wings. Because I think of myself as someone who is strong, someone who perseveres, and someone who is loyal (see Fawks from Harry Potter). What is a better symbol of strength and perseverance than the phoenix?

 I'll let update you as the tattoo idea evolves.
