QuoteAs in my example, there are many things we can't change ever, bone structure, hand size and shape etc.
This is false. I may not be able to, and you may not be able to, but there are already young trans folk out there who are growing up with skeletal structures that they are not going to hate, thanks to the wisdom of their parents and doctors who have allowed them access to the treatments they require to avoid the unwanted effects of endogenous hormones. Some such individuals could be reading this thread right now.
Hand (and foot) size and shape are also things that many, though not all, trans guys report a change in once starting testosterone. Even height can be affected with an early enough start.
QuoteAll are sex markers of a body type that will go with us to our graves.
And there are other non-hormonal, biological sex markers that would be read the way we would prefer, after spending enough time under the influence of exogenous sex hormones.
QuoteI will never be able to get preggers or have a period, you will never be able to get a woman preggers
You may never be able to get pregnant, but there is every chance that I will be able to get a woman pregnant, given the desire to do so and the financial means to achieve it. The science is nearly there. Do you mean I will never be able to impregnate anyone using the same method through which I was conceived? probably not, but there are plenty of people born with testicles who will also never be able to get anyone pregnant that way, either.
Further, it happens very rarely, but it is also possible for someone with two X chromosomes to have the SRY gene translocated onto one of them. These individuals have testicles and are assigned male at birth, but if a simple chromosome test was run, they would be told that they are female, despite the bulk of physical evidence to the contrary.
Biology doesn't care about the binary. And the idea that "you can't be ZZZ because society doesn't agree with you" doesn't carry a lot of weight with me, either. For one, society is not monolithic. Two, I am part of society, and I am a greater authority on who I am than any other member of it. And three, appealing to popularity is indulging in fallacy.
To the original question, I dislike the degree to which my genitals were feminized prior to birth. While they are not and never will be all they had the potential to be, they are masculinized. They are not feminine. I want what I have to be manipulated into a different configuration, and plan to make surgical adjustments when I can afford it.
