I preface what I'm about to write by saying that I have no idea whether I pass 100% of the time, but I can't recall the last time I thought I might not be passing. AND I want to say that I have great admiration for those who might not pass 100% of the time.
When I decided that I had to transition, I knew that I was undertaking the most significant project of my life and was willing to commit as much time to practicing as needed to undo masculine socialization and was willing to go to almost any financial extreme available to me to alter any non-passing physical features. I was lucky enough to have the available credit (if not the cash) to allow me to do so, if necessary. I do NOT wish to suggest that women don't pass because they haven't worked hard enough. I'm merely trying to convey that to my mind anything short of full passing was unacceptable. It was essential for the way I wanted to live my life. AGAIN, I'd be horrified if anyone here read my attitude as a referendum on the behavior or attitude of others. I'm trying to give honest feedback about how I felt. And how I continue to feel about me.
