I don’t go to the can to hang out, or be social. I go there to wash my hands and rid myself of biological waste.
Honestly we could dump the whole gender thing entirely and have men and women all doing their thing in the same tiled room. Unless it’s an old sports stadium with the trough (BTW I do love these for their pure efficiency, but this IS the only restroom configuration where you will likely see anybody’s private parts) you aren’t seeing shit, so who fucking cares?
Period, end of transmission.
