Hi Chunk. Welcome to Susan's. By all means, post away. And don't worry about stepping on anybody's toes. We tend to just smile and keep on dancing.
I get the feeling that what you're seeing is the "extreme" side of male and female (macho and ultra femme). Some people act like that naturally, and some do like to act that way. But there are many ways to be male or female.
Stepping back from the extremes, most people are told that they're a girl or a boy and what that usually means, and on the whole it just feels right to them. It isn't something they think much about, if at all, for themselves. But some people feel that isn't really right in their case. It's not something anybody tells you, it's just something you know.
How do you know you're an androgyne? That's something you come to know for yourself. You identify with others who identify as androgyne so therefore you must be an androgyne too. It's really no different than any other identity you have, political, social, whatever.
As Ethan and Marq and Mia said, just be yourself. That's really all you can be. Whether you're female, androgyne, or something else, first and foremost you're Chunk. And that's a good thing to be.
I don't understand what you mean by socially inept. If you feel comfortable, please tell us more about feeling socially inept versus being an androgyne versus being female. It sounds like you have a million questions you're dying to ask. We're here and we're listening.
