Seeing as how things are already complicated enough with just two sexes, what would happen if there were a third sex? How would we define heterosexual?? Homosexual? Would we have to come up with new terms? Would we both male and female be compatible with this third sex? Or just either male OR female? What would define this sex? What kind of anatomy would be specific, what kind of chromosomes? What would call this sex??
Some random contemplations.
