Online discussions I’ve seen on this subject make it sound like it’s very location specific when one is routinely worse than the other. I switched public restrooms when I transitioned ~4.5 years ago. My experience has been that both peak at the same level of gross, but men’s restrooms were gross more often. A busy enough restroom will inevitably have a user who doesn’t know how to manage their body in public, but men’s restrooms always seemed just a little more casually dirty. So maybe you should have been wondering who the fuck among your coworkers kept blowing up the women’s room x_x Because it’s not a gender thing. You just had a serial wall shitter who happened to be a woman.
