Womb, as I think we discussed earlier somewhere this move away from full GRS seems to be occurring in increasing numbers.
But my suspicion is that it has more to do with a fundamental difference between those who are transsexual, who consider the need to adapt the body as far as possible as not an option but a necessity, and those who are transgender and so using any physical changes to modify appearance in a cosmetic way to aid gender identity presentation.
I know from the outside looking in there probably seems no major difference here, as it looks almost like a technicality. But from within the difference is very stark.
In terms of the reason for transition in terms of the individual - one is basically following a drive to change body to match mind. Hence the popular talk of 'sex change' and 'trapped in the wrong body' that is rightly decried as a cliché, but exists for a reason. It is an apt analogy if you are transsexual.
Of course, we also completely realise that what we are doing is not changing sex in any biological sense. Only too aware. It is the biggest disappointment of our lives and we have to live within its limitations forever. We are just matching up as far as we can out of instinct rather than making presentation easier.
But if you are transgender that seems more a desire to change your mode of expression and there will be less of a need to adapt the body.
Looked at this way you can probably see why one group would be much more concerned over trying to 'cure' the body dysmorphia whereas the other probably just wants to do enough to pass and integrate but not lose anything too fundamental or put themselves t risk with major surgery that for them is an 'optional extra'.
I cannot imagine how any transsexual, if they were physically well and had no other factors involved, would wish to keep their penis.
That seems to me a complete contradiction in reality.
If you are okay doing that then I have to seriously question that you are transsexual, though I can accept that you may be transgender and wish to identify as female and not see anything odd in acting female whilst remaining visibly male.
And because whatever causes you to be transsexual - and I don't know that, of course - is by the looks of it pretty rare and has displayed numbers in the hundreds that appear reasonably consistent over the past decade or so and that also are not miles out of kilter with what they were decades ago, the apparent prevalence of people transitioning physically is falling.
Not, I suspect, because the numbers are falling in actual terms, but because the numbers of those who are transgender but not transsexual have in that same decade taken advantage of many things.
The greater freedom of expressing as gender fluid. The possibility to use the GRA and equality act to become legitimised and the activist movements that have sprung up. And the much wider debate that has even brought many children into the picture being faced with these options for the first time.
So if more and more of these are using that fluidity and transitioning in the transgender sense so without the desire to go far into the physical transition the balance between those who have GRS and those who have not shifts and it looks like it is falling.
When it is only falling because other things are escalating dramatically.
