I would like to suggest that you talk with your psych, and endo about it (assuming you use the VA ones). If you start planting the thought in their ear, they might actually take the hint. You could also ask them if there is a trans friendly urologist there. That was what I had to find first. I found one of the urologists who was not only trans friendly, but had worked with a lot of trans people prior to being at the VA. Once I got her on board, she talked with the endo staff, and the psychologist who heads up the trans support group.
You shouldn't have to do all of that, but if you at least talk with endo and psych they will keep their ears out for you. If they say it can't be done, ask them to contact their counter parts at the VA hospital in Seattle.
