A lot of the shops in my town have gender neutral changing facilities because they're small shops, so not room for big banks. A lot of the shops only have one booth, and our swimming pool only has a mixed changing room so it's not that far out of the way, and I'll admit I've not felt threatened of venerable using them. That being said, these have doors, not daft ill fitting curtains.
Our of interest (genuinely asking, not trying to be a goady fucker), do the people who feel uncomfortable about using mixed changing facilities feel that way because of the way the facilities are set out? Would you feel okay sharing the cubicles if they had proper doors on?
