Thats an interesting question, I agree with and relate to everything stated above.
With me, I definitely started out not understanding if I was transgender or not, and didnt think I felt dysphoria and thought I couldnt be validated as transgender. I dont think I even understood what dysphoria was.
Turns out after all I DID experience dysphoria, it became more obvious when it clicked and I realized I may be trans. Looking back I did not like puberty. Looking back I was apathetic to certain aspects of my body, I didnt like it all that much, it just seemed 'off'. I was "okay" with being a girl, Ive never considered myself ugly and I saw myself as fairly attractive, I kind of just ignored it and lived with it and was myself, I was "okay" I often told myself, I wasnt highly depressive or experiencing suicidal tendencies. Thing is, I realized I like the idea of being male even more, that it made me happier. The idea of top surgery greatly appealed to me and I started to dream of it, and I realized my small chest that Ive always been confused about and ungirly is my greatest asset until I can transition. I liked the idea of being a feminine male, I knew I wasnt going to change myself in drastic ways and being a guy that way helped me realize where I lie. When I started realizing I could go from "okay" to happy, I started to feel better.
I think I never realized it, but the dysphoria seemed to clamp down on my confidence levels, Im a little less anxious and a little more confident being a guy. Funny how I never knew that all along.
Dyshoria to me was just discomfort, nothing extreme like suicidal tendencies or depression, but a lot of the times a deepset feeling of apathy and resentment, of not caring all that much and trying to find ways to care about myself even though I knew I was attractive. It was learning to handle the strangeness I felt with certain traits of my body.
Ive come to accept some things. I still want top surgery, but Ive accepted some feminine or female traits as part of myself as being a man. I still am small, have a little bit of a female figure, and female genitalia. Im okay with these, and the last one mainly because that cannot easily change. Ive learned that despite these Im still a man like I feel, and Im still happy and comfortable that way and learned to accept those things.
Most people might consider the fact I can accept certain aspects of myself and be happy as odd, but the important thing is I look like a male, act like a male, feel like a male, and have changes in masculinity where it counts.
I find it weird when people dont feel any kind of physical or social discomfort, otherwise it just seems as if they are doing it for fun, for recognition, or because of misinformation. I understand people can also just be confused as I was, though. Therefore no matter how skeptical I am of someone else its important for them to make their own decisions on what makes them happy. Most people need to talk out their feelings and be informed when deciding, and in the end its about what makes them happy amd thats up to themselves to learn truthfully.
