So, my therapist says he will probably give me my T letter next month, but unfortunately, due to insurance issues, I may have to put off starting transition until January or February. My goal was to be more or less passable by September of '09, when I'll be starting back to school. My therapist, though, has said that if I want to be sure to pass, I should give it at least a year.
I realize it varies from person to person, but I wanted to take a short survey of how long you guys were on T before you started being Sir-ed more often than Ma'am-ed.
