I only went to therapy because it was necessary to get testosterone, and it really p*ssed me off being obliged to disclose myself with sometimes very private or even intimate topics. We had only two gender therapists in my region, and one of them was known not to get along with FTMs. So I picked the other, and it happened to be a male who was a nice guy, but with old school convictions (he requested 1 year RLT everywhere before getting hormones - I hated lying to him all the time as I had a horrible passing due to my physical shape no matter what I tried, and requesting everyone, even at work, to call me by my male name as long as I looked female seemed totally silly to me). Otherwise, this guy was okay.
Him being male was fine with me, a female gender therapist might make me worry whether she gets along with me talking all the time that I want to get rid of the female body parts I have. Because if I were a female gender therapist and had to deal with FTM clients I would probably get horrible nightmares with my female parts being cut away etc.
