I'm gender dysphoric, although I decided not to transition for a myriad of reasons. But I do write a lot of fantastical scenarios that go in a lot of odd directions for things that serve as an outlet for my non-transitioning self to compensate. Hopefully, my angle on some things does end up resonating with trans readers as well as others who don't adhere to a binary, although I don't go nearly as far with it as I could. I do tend to write a lot of women coupling together as if it were just a natural thing in my universes to do.
Even so, on the trans side of things, I think a lot of that is partly the nature of how a lot of trans-related fiction from my generation was made. Just about everyone in my similar age group in all my trans-friendly circles in high school and college were heavily influenced by Ranma 1/2, this idea of a cis guy becoming a woman, and not enjoying it at all, but having to deal with it. It's still profoundly prevalent in a lot of writing that I myself do, as well as with other writers off-site that I'm familiar with whom I'd known for quite a while. I also mod on a couple Discords where it's very similar in the roleplay sections to the Ranma experience, at least for people roughly my age. For the newer generations joining those servers, they seem to be happy with ditching that premise and just going all-in with embracing change, so I imagine my viewpoint comes from being young when trans concepts at least weren't well understood nor accepted as much more than a punchline for jokes, rather than the more progressive outcome of today.
My worst offender for the Ranma trope is one I literally wrote to be similar in regard to Ranma, called
Coinbearers. The premise is that a magic coin boosts a user's talent every time it's flipped, but they are transformed between male and female depending on the outcome of the flip. So the change is definitely meant to be a hurdle rather than anything else. I do try to not write it in the "oh no I'm a girl I hate this" way, but it does have similar ideas to other transformation-like stories where the main character is introduced to ideas like women's fashion and other things without having been interested in such things before. From my particular angle on the gender spectrum, I like it a lot, but I guess I'm like a trans girl in arrested development or something so the 'first time' stuff can be thrilling.
I'll have to give things a go with an explicitly trans main character on some of these stories. Just about all my stories could support a path like that, where the supernatural or scientific means of transformation is part of the goal or wish fulfillment rather than a side effect, and then the story would shape up quite differently depending on which of my stories this occurs in. Just about all my stories could support plots like that where there is some other challenge that the main character has to endure as a result of the story's devices, I just have to think about the approach in a friendly way.
