Hmmm...
I think for any kind of condition, we will all read books, the internet and convince ourselves we have this condition or this illness. Self diagnosis is perhaps a step on the road, but until an official disgnosis is made I guess, you can not be classed as anything
Once you have that diagnosis as a Transsexual (after the absence of all other possible causes), I guess you then start treatment, hormones in the main. Electrolysis, voice therapy etc..at this stage I would consider this to be pre-op, a diagnosis followed by hormone therapy... followed by RLE and then surgery.
I knew I was different, suspected I was TS, but denied that for fully 20 odd years, because the consequenses at times where to frighteneing to even contemplate.
So to keep on topic I guess , I was a potential TS, in denial without a diagnosis... Hmmmm
