Agree with others about that dreaded P word...
It often seems to be symptomatic of lack of belief in the reality of your own identity. Which paradoxically is the very thing which keeps many from actually achieving what they are talking about.
However if we accept that being born trans or intersex will involve some degree of anatomical discrepancy, at very least pre surgery, then it is a nice feeling when you get to a point in life when you can look back and realise that you can't recall the last time that anyone questioned you.
Coming up to medical school this year I kind of ruefully admitted to myself that even nearly 30 years post surgery there had to be a chance that some bright student or well informed specialist consultant/lecturer might put two and two together. I am happy to say it never happened.
When we had our tutorial on trans & intersex conditions, the doctor leading the session was at first puzzled that I seemed so well informed, and then frankly completely and utterly gobsmacked, to the point of speechlessness, when I chose to out myself to him and the class, as gender reassigned Partial Androgen Insensitive Intersex, for the purposes of showing them all how easy it is to be prejudiced. Of course none of them had ever expected to find such a person in their own ranks! They know better now...
And as I have still been elected by them as leading student for the year, you can surmise that there is no lack of acceptance. In my recent exams I thankfully scored towards the top of the class, and this despite being rather older than my compatriots.
