I'm Mary T.  That is not my birth name but I wanted to be called Mary for as long as I can remember.  I told my mother when I was about four years old, and I can still remember the conversation:
Mum: "No, you can't be called Mary.  You're a boy!"
Me: "How do you know I'm a boy?"
Mum: "Because of your teeth.  And your favourite colour should be blue, not pink!"
I thought blue was quite nice, too, so my favourite colour changed to please my mum.  I didn't believe her about being a boy, though, and I thought that it was just my hair and clothes and name that made me a boy.  If my teeth were also an issue, I could just keep my mouth closed.
My mother's clothes didn't fit, and I just had a brother and no sisters.  To be a girl, I took off my clothes and covered my hair with my mother's headscarf.  Sometimes I wore a towel like a dress.  I thought that I was ugly dressed as a boy but quite pretty as a girl.  Since I thought that I looked like a girl when I was naked, you would be right in thinking that I didn't know much about the facts of life.  I was often caught during my experiments, and my mother was always contemptuous rather than angry.  It didn't stop the need, though.
When I was eight, I made a plasticine model of a nude woman and showed it to my mother.  I think that I was trying to shock her.  She wasn't angry, but she did tell me that the model should not have a willy, as girls did not have them.  That was news to me, and for the first time I realised that I really was a boy, even while (especially while?) I was naked.
I really did try to be a boy.  My admittedly generous parents brought me loads of toy soldiers and I could have any comics I wanted, except for girls' comics such as Bunty, Princess and June and School Friend.  (I still read them whenever I could, especially June and School Friend.)  I didn't really like running around with toy guns, but I spent a lot of time making up stories with the toy soldiers.  I still needed to look like a girl, though, and I was often caught trying on my mother's clothes, even though they were too big.  My behaviour wasn't mentioned to a GP, let alone a psychiatrist.  I think that my parents were too ashamed.  I was, too, but I couldn't help myself.
When I was twelve, I started to grow pubic hair.  I didn't know that girls also had it, and I contemplated suicide.  That was unfair of me, as apart from my "problem", my life was idyllic at the time.  We lived on the edge of a subtropical coastal forest with monkeys and some antelopes, and there were dolphins in the sea.  I even had a friend who was like me, and we secretly dressed up whenever we could.  Eventually, my family and I moved away, and I lost touch with my friend.  On the bright side, when I eventually started growing facial hair, I had already passed the suicidal stage.
At high school, I tried to be as macho as the other boys.  I avoided boys who might be like me, as they might have tarnished my image, and I got beaten up enough while I was trying to act manly.  All of my front teeth were chipped by punches.  Even so, my nickname among some boys was "Homo".  I never again had a friend like the one I dressed up with.  I acted as though I was very attracted to girls, but to this day I have never had a real girlfriend, or boyfriend for that matter.  I'm not a "hunter" in that way.  I still had the urge to dress as a woman, though, and I was sometimes caught.  
When I was about twenty, I was eventually sent to see a psychiatrist.  I did not enjoy the experience, which I found very humiliating.  The psychiatrist was eventually satisfied when I admitted that I was a "poof".  He discussed my case with my mother, and that is probably why she bought me some second-hand June annuals and School Friend annuals, even though I was too old for them.  I felt that I should reject them, but I liked them too much and still have them.  My mother never accepted what I am, though.  I tried to resist the urge, but continued to dress as a woman when I could.  Sometimes I was recognised and reported to my mother, who was then particularly ashamed and used phrases such as "I despise you".  You shouldn't think that she didn't love me, though, and I certainly loved her, and cared for her during the last few years of her life.
At work, I tried to appear manly, but colleagues sometimes suspected something.  One conversation went:
"From now on, I'll call you Manly D...".
"I'd rather you didn't.  Some people might think that you are being sarcastic."
"Do you think I wouldn't be?"
At other times, I was known as "Mother", or "Nana" (because I allegedly looked like Nana Mouskouri").
I never had SRS.  I could not have faced my mother, and in any case I never wanted to see another psychiatrist.  My only concession to being transgender now is to use hair removal creams on my face.  I had a feeble moustache at one time in my life, but my hair was too fine to grow a beard.  I no longer wear obviously feminine clothes, even in private, but I am secretly pleased when I am occasionally "mistaken" for a woman.  I am short and have very small hands and feet for a man.  Although my parents are dead, I know that there is no point now in having full SRS.  I will never have a lover.  However, although I think that my testicles don't function anymore, I am still looking for a way to have them removed without consulting a psychiatrist.  I don't like my penis either, but I think that I would be satisfied with an orchiectomy.
And that is my story.  It is too long, I know, but I think that it might strike a chord with many older transgender women, from an age before transgender girls were allowed to go to school in dresses.
