Hi Emily,
I've not had many female doctors over my life but I love the few I did have. Yes, I feel that with my therapist a female would be the easiest for me to come out to and be honest with. That's not to say a male therapist would be bad. I've always been able to relate more emotionally open to females.
Some seem to just want to push through and get the referral and HRT prescription. I prefer to look at the therapy as a chance to consider our path, reason it out to the best of our ability, and to work on coping skills. Because being transgender will never be the easy path to walk.
Another aspect is I don't know how my wife will take that I have to walk this path. So, I'm hoping that therapy will help with this as I'm only now becoming honest with my self, and I can't be honest with her until I'm ready. Ultimately, it seems to me that there's more harm in closeting our behavior. A very high price in constantly changing between the two, and/or keeping our female side repressed.
Best of luck Emily on your journey.
