Hey Rebecca, very interesting question / post.
Well here goes:
Being a man means, well very little but very much mostly do to the fact that i "LEARNED" to be a guy to stay hidden for so long-unlearning that is not something i can do in a month or a year..
When i was like 8 my sister caught me wearing one of her bras.. Later that evening the dreaded talk with my mother she was short and pointed about it she said whatever was going on to stop it she never wanted to see that again and if people found out they would think something was wrong with me.. Hmm 38 years old and that little speech of hers was like a bad seed planted in me! To me a trauma i have not outgrown yet. How cruel for your own mother to tell you this at such a young impressionable age! Anyway so i tuned into being a guy (and kept the girl in me hidden and private and she never came out to anyone until i was in my mid 20's)
Thus being a guy is something i know a lot about, funny how good of a cameleon I've become in my life, i weave an air of mystery to others who see or meet me. I am one of those people who say they cannot immediatly put their finger on me?

GREAT!
Being a man to me means being a lie, living a lie, being fake, not being technically (physically real) real. It also means I've found ways to manipulate the gender of being male physically to a certain degree.
I would never say i have the best of both worlds, that was said to me by a friend once trying to cheer me up? I thought the best of both worlds? When all i ever wanted was normality or even lifes worst thrown at me in one world...
What does being a woman mean to me? I guess eveything, more powerfully
EVERYTHING... I dream about turning back my birth and being done right, about having a real womans body, being able to give birth, genetically have a menstral cycle, having hormones, long hair, features the works and -etc...
And as i have said I am very complicated gender aside i am a perfectionist, obsessive compulsive to a degree, some days more obsessive about things and other days more compulsive about things! This just adds to an already complicated life! Some days driving into work i just wanna turn my car around and drive the other way? Problem is where is the other way a road to somewhere i cannot go at this time!
I think there's hope some form of it anyway.. I pray my mother a long life but if the good lord takes her from me then i suspect i will make some dramatic changes.
Cool post Rebecca!
