Apart from a number of Sydney girls (7 or 9) who use this forum and who I've met face to face....
I've known a trans guy for about 12 years, he was pre transition when I met him, started transition about six years ago now I think.
I worked with a trans woman who was pre transition and wasn't out - I only found out about her a few years after she moved to another job and transitioned there. Haven't kept in touch though.
I know about three more women socially, two who I see regularly.
And of course there's a number (male and female) I've encountered in the endo's office and at the gender centre or walking down the street. Sometimes it feels like I can't three steps without tripping over a trans person!!
