In Heinlein’s “Friday”, America has balkanized and broken up into several separate countries. The Country of California only allowed unisex bathrooms. The movie version of his Starship Troopers had the troops showering coed, but I don’t recall that in his novel.
Yeah, and the one actress in “Troopers” that should’ve been in the coed shower scene (Denise Richards) wasn’t, and the one with the flapjack boobs (Dina Meyer) was.
