I do hope you talked him through the whole thing.
how women have to remove clothing, often several layers, or adjust clothing, lift it or lower it, from their bodies to pee, poo or change sanitary items
how women having a period then have to change sanitary items, be it pads, tampons, or mooncups.
how women then have to dispose of said items
how women then WASH THEIR HANDS because we are not scuzzy people who walk around with wee or blood on their hands.
Most men walk in, unzip, grab their penis,pee, replace penis, zip up.Leave. No waiting for a vacant cubicle , no fancy schmanzy hygiene stuff to do like dealing with blood and hand washing.
