Could it be fear of stigma?
I'm currently read as a non-gender conforming female by most people. Arguably there's a certain degree of stigma there already. More importantly, though, I have experienced all manner of stigmatisation for all manner of things--seizure disorder, mental illness, certain aspects of my faith, being a kinkster, being a switch... the list goes on. Sometimes this has lead to harassment. Sometimes--mercifully rarely--it's lead to violence. Stigma is not a stranger to me.
Could it be fear of losing family and friends?
Anyone who would reject a person for being trans is no great loss. I'd be perfectly happy to scythe away any undetected bigots in my orbit, including bigots I happened to share genetic material with.
Could it be the desire for normality?
Desire... for..? Hah. Haha. AHAHAHAHAHAHAHAH!
In all seriousness I guess I might present more towards the "masculine" end of the spectrum if I didn't have to worry about jobs, etc, but I already wear very androgynous clothes most days. If I look female it's because my body betrays me, not my men's jeans or workboots.
Fear of change?
I've lived in 3 different countries in the last decade, and 4 cities. I've gone from being a chaos magician to being a heathen. I've gone from electronics engineering to teaching English. I've taken initiation as a somaferan. I've made untold changes to my life and will continue to do so.
Fear of 'boxes'?
Boxes? Great! Is it a little box you can put jewellery in, or a big one you can pretend is a spaceship? Or a medium-sized one for biscuits or interesting rocks?
More seriously: I hate the idea of being crammed into the "man" box. I've spent a lot of time locked in the "woman" box, and I do't reckon the "man" box is a whole lot better. It might be a little nicer to have a marginally-better-understood label to hang on myself, but only a little, and only marginally.
Fear of transition not being fulfilling enough?
Well, this makes more sense. I mean, given that I'm an androgyne I doubt I'd feel particularly fulfilled as a man. I want to stop hating the flesh I'm in, but that doesn't mean a full transition to male. I'd like a more androgynous body, which in my case means more male-seeming, but not quite a man's body.
I'm not an androgyne because it is somehow more comfortable or safer than being fully male. In fact I find it tearingly, wrenchingly uncomfortable. I fought a long time before I would accept that identity, but in the end I was forced to accept that it is who I am.
I have to say I'm a little piqued by the implications of this thread. I mean, if people want to discuss "is androgyne a legitimate gender identity" then that's fine, but does the discussion always have to happen in the Androgyne Talk section? I thought this was for androgynes to talk about being androgyne, not for other people to talk about us.
