No. We aren't a third sex and stop using us to push your narrative. I'm tired of repeating myself on the manner but if you actually did your research on the matter you'd find the need to correct us came from putting us on a spectrum, or in otherwords othering our bodies. https://twitter.com/dani_tillotson/status/1335510407314894849
When one is not considered male or female they are considered a male pseudo-hermaphrodite, or female pseudo-hermaphrodite according to our "good" friend Anne Fausto-Sterling. Humans in nature cannot be true hermaphrodites, although ovotesticular used to be called that.
Intersex surgeries are still done but at a much rarer scale then before, especially compared to when you were born which I imagine is similar to me judging by the age you gave and the fact you -somehow- carried to term three children despite having such a "crippling" condition.
The condition you are claiming to have is extremely rare because in practically every recorded case, it has killed the fetus or an infant and the only case I can find of a live individual is a 'dead' link that results in a mentally handicapped male. https://pubmed.ncbi.nlm.nih.gov/12868076/
You also claimed that you had male genitalia x-rayed, which is impossible as the wolffian ducts and their function are purely external. Unless you mean internal gonads which are subjective, but if you truly had "functional male" gonads you would have never succeeded pregnancy.
Also it is interesting that "intersex" people are advising to trust in the very same people who othered us for years, created and justified both the Prader and Quigley scales which have been used in the past to justify conforming an infant born with a CCSD's genitals to fit.
Fit what? An imposed binary implied on sexual characteristics, showing the issue isn't the binary nature of sex but the backwards idea that sexual characteristics are what make one a male or female. That one has to look a certain way to be male or female, or they are an other.
The very system you are defending, is the very same system utilized to imply intersex people aren't male/female and need "surgically corrected" to conform. You can slap rainbow glitter on it all you want, it doesn't change what this system is.
On top of that, you're also making an impossible and unbelievable claim in terms of neuroscience, considering neurosurgery is "typically" regarded as a last resort option.. in other words: Life or death situations.
Brain biopsies which are often done in regards to brain cancers, Decompressive craniectomy, Bilateral Cingulotomy[Very new, experimental even] a questionable treatment for OCD and of course other options. The thing is, neurosurgery is not proposed for what you are claiming.
I don't know to what degree of truth your story holds aside from the fact you were a "cis female" and you went through three pregnancies but by definition your condition claim does not line up with what facts and research is currently out there.
Neuroscience is not advanced enough to do what you claim it is. You also claim to have a normally fatal condition that isn't typically considered intersex on the rare incidence of survival.. plus it ends up in numerous issues you clearly do not have.
