Guess I'm not sure ....
I'd certainly gone full time (RLE) and was under psych / medical supervision before I encountered any groups or forums like Susan's, Calpernia's Info Exchange, TS-UK, and the specialist surgery and hrt groups.
But it all started for real when I began to self-medicate having found an internet drugstore, and sites with doseage information.
But I wasn't "green" at any point in my life.
I would have used the word "transsexual" to describe my feelings when I was just 12 or 13 back in the very early 1970's. I'd read the Jan Morris autobiography at the age of 14, and other TS biographies followed including April Ashley and Tula. I did loads of library research in my late teens and early 20's, including local university library where I came across Money's "Man, Woman, Boy, Girl" and diligently photocopied TS related articles from the bound medical, psychiatric, and sexology journals going back to the 50's .... even came across surgery manuals one of which showed graphic details of SRS as it was back in the 70's !
In my mid-20's (1986) I discovered the London "scene", TV/TS/drag clubs, and encountered other TS women, pre & post-op who looked fantastic .... I looked good too but pretended to be TV as I was not ready to turn my life upside down, shock family, disrupt developing career by coming out. In the 80's it was still something you were so secretive and "hush hush" about.
Think the net was symptomatic of the way society changed, and I was on the verge of transitioning at the same time as web resources made me realise the size of the "community" out there.
