(Coupling) genitalia is also 2 types, jack and socket. The ones that doesn't care topologically have both jack and socket. Train connectors, and hands both have protrusions to tuck in other's socket. If everyone have both, it's Asexual.
What if futa amogus? Futa either weeded out for not doing reproduction well enough with 2 separate systems or burdened with their performance outside sex, Or they weed out specialized sex and became asexual. This dynamic is fragile.
If its 3 sex and 3 partner needs to have sex together, such system is extremely fragile to have 3 individuals of different sex to be able to have sex at the same time same place.
If only 2 partners needs to be then the less attractive ones just weed out and left you with 2. If the weak one still allowed to stay but not sex, like Women Bull Cuck, congratulation, the cuck is better off sterile to maximize all the work no sex, and its easier to influence one to be rather than born to be. And if they are sterile, it doesn't matter they are male, female or third sex. That is what ants and bees chose.
And further specialization are done outside of body and genes, construction of society and development of tools.
2^n specialization is done on different level(from base pairs, 2 set of chromosomes, recessive and dominant phenotype ...) and parameters and far more expressive than one scheme of 20 selections. Every 1 dimension parameter have 2 directions(extremes). For each job just fill out parameter criterion like Male, Strong, Dumb, instead of a special sex.
