Getting good gender related therapy is, well, therapeutic!

I think if the therapist is experienced with gender issues you should find the sessions helpful unless you just do not click personality wise.
You can also check YouTube and other sources for videos on what to expect from gender therapy.
They are there but I have never watched the ones on YouTube.
I will say though, based on my experience, that I think that gender therapy is a helpful process to go through.
