I recently visited a country with self ID. Most places in one city in the country still had separate male and female toilets.
However in the other cities I visited there were either corridors (often located in dark basements or a floor or couple of doors away from the main restaurant/ pub/ shop floor etc) with unisex cubicles opening onto a shared sink area or cubicles designated male female or anyone with a shared sink area.
I hated the shared areas - it didn’t feel safe being alone away from the main drag with random male strangers.
At a more frivolous level, I didn’t feel comfortable adjusting my dress, putting my lipstick or perfume on or brushing my hair in the mixed sex sink area. The men - particularly those young enough to be my sons) also seemed uncomfortable with sharing a sink space with a woman their mum’s age putting on her lippie. Not great.
I also had an amusing interaction with a bloke when I was queuing for one of the female designated cubicles and he observed that two male designated cubicles were free - he said, rolling his eyes- you should just identify as male!
There were also a few places - as commonly seen in the U.K. - that had fully ensclosed unisex cubicles with integrated sinks. These were mostly clean- ish but again entailed queuing in a sometimes remote area with random men.
