Will Heaven bathrooms be unisex?
Bathrooms being tied to physical body functions, no bathrooms in Heaven. Since procreation is no longer one of the functions either, just a gender-free somewhat amorphous wraith floating free of constraints like gravity or any kind of atmospheric movement, without either mass or quantifiable substance, but bound within a field held together by psychic force.
A little hard to exert domination over others under conditions like that.
Soap bubbles do not have sex.
