Pros over male/female classification:gender neutralseparates genitals from sexdoesn't remove the sexual implicationsCons:none
I'm going to go a different direction and argue that the RS232 has always been the most androgynous and third-sex of the connectors because:the female connector is most frequently the one that's a cablethe male connector is most frequently directly connected to an appliancethe male has the pin prongs, but is almost always recessed.the female connector has the the prong holes, but almost always juts out.Who's connecting to who? Who's the top and who's the bottom? Who wears the pants? No one knows.
