I hear people talking about being trans without having dysphoria. Personally, I'm not sure that's possible. But what does happen, and I know this from my own experience, is that it is possible to have dysphoria and not recognize it for what it is.
So, when I was seven years old, looking at pictures in a magazine and wishing I was the girl in the picture, I didn't call it dysphoria. It would be more than 50 years before I recognized it for what it was, but it was dysphoria.
When my teenaged life sucked because I was different and didn't fit in, when my young adult life was miserable because I was the only person I knew not dating or in a relationship, when I felt self-conscious about not appearing to be macho enough for my peers, that was all dysphoria, though I didn't know it at the time.
For us older transitioners, this stuff comes into focus only in hindsight. I envy the little kids for whom it is so clear.
