I think the "Informed Consent" stuff is a good idea.
I had to deal with a nice, but old-school gatekeeper as there was nobody else around in my region who was okay and who could take care of the gender sh*t. I never wanted to be in therapy for the gender stuff, and even less to be forced to go to therapy to get on T. But no other way to get at hormones. Well and he requested 6 months real-life test before hormones, full-time of course, one year before I ended university so what's the point outing myself just before it all ends? I just found that plain stupid. Cause I mostly did not pass before hormones, no matter what. Moreover, it's a stupid request for FTMs - most will pass on hormones, but not before, point. Well so I had to lie at him consequently. As I had my own mind and did not adhere to his strict rule and wanted to be free to transition my own way (official German rule by the way, a strict & stupid deviation of the SOC). But I needed the PAPER for the testosterone, so I had to play the game. And had to tell him some stuff about my sexuality as well, but of course I did not tell anything about all my kinks and stuff in order not to be checked in detail about that crap. No one's business but mine. My paper says I'm a bore in bed but have used strap-ons on my ex-girlfriend and one of my ex-boyfriends. Haha. That's maybe 2% of what's interesting about my sex life. Sorry, but I cannot open my soul to a gatekeeper, that's a no-go on it's own.
The "gatekeeper function" of my old-school therapist had only one effect on me - it was counter-productive. I wanted to wait one year before getting on T anyway, just to go sure, so no potential trouble from my side. And I cannot stand being patronized about HOW exactly I have to transition, especially not the RLT before hormones sh*it. I'm not gonna go into details here, but this gatekeeping ripped open traumas again which had healed before as it happened to push the very few buttons you can push to really freak me out. And for a while I really thougth I needed a therapy to get over that therapy as I had tried to get through that stuff without being re-traumatized as much as I could but I could not avoid that effect completely...
Oh and his method to check whether I still had dissociative identity disorder (DID) did not work either. (I had DID, but mostly cured by then). He tried to trick me into believing it was another day of the week than it was, I corrected him and he was relieved. He made that several times. Other people of my self-help group, when I told them and thought the poor guy was just getting old, told me he always does that to rule out Schizophrenia, DID etc. I could have passed this therapist's test with my DID being full-blown and us being hi-jacked by a personality wanting to transition. As we always knew which day of the week it was when someone asked, especially in "trial mode". You always find someone inside willing to answer that kind of questions once you're enough people inside.
So I think this "informed consent" thing is useful.
