I think it would be a waste of time and money, given that it's generally accepted that we are born this way. Even before I worked out precisely what was 'wrong' with me, I knew I was different from the boys I associated with.. Then at age 12 I worked it out - and promptly jammed that idea in the deepest, darkest corner of my mind - only to have it come back and bite me last year.. I'm trans, always have been and, despite what some around here will say, always will be.. Past events in my life have nothing to do with it.
