It would lessen so much complication if that happened yeah.
It would be awesome to just...suddenly magically wake up cisgender. Especially back when I lived with my parents. Like, imagine that, I cant control being transgender, and I have to accept some things about myself (I can be a male, but I cant truly change my past experiences living female, or my chromosome, or my genitals realistically), so if I suddenly woke up a boy and it was not in my control, THEY would have to accept it instead. It would be a shock, though. I'd have to deal with the shock or drama of those around me needed to come to terms with the idea that I'll be stuck that way forever.
Edit: I had not realized the question was saying if everything else would be transformed as if I was male too, including people around me feeling as if I always was and all my identification being that way. Even better, yes all the way!
It strange to me that so many wouldnt change immediately. I mean...I love all the experiences that make me who I am that I wouldnt have otherwise, but I am a man, not a transman. Its strange to me that people would choose not to live that way.
Honestly I only tie with the trans comunity
because they have the same issue I do, not because I have some pride in being the way I am.
Now had the question been changed, what if I was born male and raised that way all my life, well...it would be nice but at the same time Im not sure how it would be. Its an entirely new experience and Id be a new person. And Im confident in the one I am.
Noooow as for if I was a cis female. Its even harder to imagine this, I could only ever imagine wanting this as a way to keep the peace. I would only wish I didnt have these awful dreadful feelings of changing my gender because its wrong and bad and frowned upon. I didnt ask for these feelings, it would not be me to be female, but it would be "correct", and I would never have to worry about social ostracization
