i’m returning to an old worldbuilding project i made in highschool. the people in it were constructed unnaturally and don’t have the same biological limitations as regular humans, so they have 4 natal sex categories: the typical perisex female and male, in addition to an androgynous sex (i call them ambale in my notes) and a neutral sex (likewise dubbed neutrale)
i have a general idea for what a perised ambale person would look/be like (bigenital, capable of both becoming pregnant and impregnating others, capable of breastfeeding, both feminine and masculine secondary sex characteristics) but i’m stumped for ideas for neutrale individuals. nullo seems the most obvious to me, but that would only be what their genitals look like and not their other sex characteristics
if you were born as a neutral 4th sex, what would your ideal primary and secondary sex characteristics be?
Maybe they can have a non-sexual reproduction protection niche.
Perhaps they are very strong and thus can protect their clan, or they can provide milk better than the others.
Alternatively maybe their bodies have a divergent metabolism that results in a low-slow burn so they end up being long-lived historians/story tellers/teachers/experts.
Lots of options for switching some things around in the body that have outsized impact in ancient tech level societies that become less important as they modernize.
