Well the only solution then is to build just one big bathroom with lots of urinals and stalls.
Togetherness will never be better than the last thing couples don’t share they finally can, bathroom time.
Make them stall-less.
Men go to the urinals, face forward, don’t talk, and move on.
Take out the privacy, and the ladies will move along.
Stalls? Waste of space, just put a long beam over a trench and let them (male or female) squat off the edge into the ditch.
Men are already expected to use p*** troughs in public stadiums and schools.
