matron

I'm having trouble finding any support for the use of "matron" in the way you describe.

But, actually, no one has ever commented on the fact that I’m a matron and a man." -> Tech language is sexist and must be changed."

Asked the passport control officer, a woman with the appearance and disposition of a prison matron. >>“None of your business,” I said.

Not only is Latin mostly gendered and the Latin root of this word clearly male, but the female root "matron" is also a common root for English words.

It can't possibly work for you or my cousin working as a matron in a hospital. The algorithm basically measures exposure and the current thinking is that 15 mins is long enough to flag a warning.

Yeah, the house’s matron was fired over it - and it transpired that she’d lied on her CV about her experience and qualifications - something that seemed to happen with alarming frequency at the school.

I once had septicaemia from an infected wound, and the matron’s response was to fling a mop at me as I lay on the kitchen floor in a puddle of pus and blood while telling me to “clean up your fucking mess”. I blacked out at that point, and the aforementioned friend saved my life by calling an ambulance - I awoke in hospital weeks later.
