You question may need clarification. If your’e referring to hypnosis as a therapy tool that would be different than hypnosis as a way to feminize your thoughts.
The first would require a lot of convincing with a qualified therapist and second opinion before I would consent.
The second is not something I would do. I’ve worked through a lot of things consciously with the help of friends and therapists and already know my thoughts are feminine. That’s part of what got me to where I am to start with.
