I am using an inexperienced therapist now. So far, it's been okay. I have had to do some educating, but overall I am happy seeing her. My issues may be a little different. I am on T, but don't identify as male, but rather andro. I go to see her just to discuss primarily the stress that comes with the social reactions to my decision and my concerns about the loss of the one side of me but the happiness about the other. I personally believe that a good therapist is someone who doesn't judge you. Maybe they don't have the most trans experience, but it doesn't mean they can't help you.
We have one gender specialist in my area. When I went to see her, it was only for two sessions, then she wouldn't see me anymore because I have been diagnosed in the past, INACCURATELY, with being bipolar. She doesn't deal with anyone with prior issues??? and would not treat me, which I found odd being a therapist with years of experience and insane amounts of schooling and credentials. Besides the point, she pretty much told me that if I didn't recognize the difference between gender at a very young age (around 5) and envy males at that point, that I must not be trans. That's the specialist. Now my therapist, who is trans friendly, asked me about why I feel the way I do. I explained, she listened. I told her I am not 100% sure transition is right for me, being gender variant but not male, and she listened. We walked through it. I didn't get a "well you are wrong about your feelings" type of response. Now, I am on T, and I talk to her each session about my concerns, and she is a huge support for me.
It doesn't hurt to try this person out. You may find you need to try out a few different therapists before you find one that works for you.
