The Ultimate Superpower: Changing Genders

I honestly do no meet that in a perverted or sick way. I mean that with most sincere curiosity, and deep inner conflict.
See, ever since puberty started I'm far more aware of my gender, and the other existing one.
I am far more aware of how a woman acts and thinks, and how a man does as well.
The differences, the similarities, and the extreme amount of exaggeration that female magazines and old woman-in-kitchen movies provide to showing how much of space there is between the genders.
My belief and notice is that above genders, we're humans. People. We all have hearts, brains and bodies. We all develop them differently but that doesn't make us superior (although that's a feeling we tend to enjoy, and now I'm talking about both genders) or less important.
As a teenager, I feel somewhat immortal. It's what I like to call hormonal naivety.
As teens, we're young and cannot imagine ourselves in any other shape.
Yet soon we'll all change into women and men. Into people who think they're entirely different because they're aware of certain different biological forms, and that's when the raging man woman war starts. Where we all assume the others thoughts and feelings and judge them fast.
This is silly. I am a woman, sometimes tired of being so but none the less a woman.
Yet what does a woman mean? What does a man mean?
Different clothes? Different likes? Different hobbies?
No, that's the definition of us being human and of us all being unique. My question is, will people always be this way and perceive me like that to? Will guys make me feel like a joke because I'm a girl, and therefore according to them, different? Like in movies where nerds think girls are a whole new species?
