I am still very early in this whole process, and there is still a lot of self doubt, so I am reading a lot of literature on "Am I trans" and dysphoria.
One concept that people often like to propose in these ressources is the button that makes you the opposite gender, and, crucially, also makes everyone else believe that you have been that way forever.
I don't really like this, because my time as a boy/man is part of who I am. I would not be me without it, and despite all of the problems I had and have due to my gender, it is still part of who I am. I fought through all of this and worked to find out who I want to be by myself. I wouldn't wanna be cis, and I also don't want to cease being the me born out of this struggle.
Yeah I feel that too. Like would I press the button now? Idk maybe haha. But also I know I definitely wouldn't press the "Be happy as a cis guy" button. The button question was helpful to me early on because it was my first inkling of "Ohhh shit I'm trans aren't i" years ago, but I rationalized it away.
All in all it's just a hypothetical, a tool to get to the heart of an issue. You don't have to use it or like it
