To be honest, we don't really know if duplo's are rare or not. Ashe tells us in the beginning of the story, but those are just Ashe's words, not an objective narrator. I wouldn't be too surprised if in reality duplo's aren't that rare but just uncommon, but that duplo's are just taught they're rare for some reason (most likely because of the negative reputation they have).
well the way Ashe seems to describe her own sexual needs , it sounds to me like Duplo's have had an image of being sexual predators due to having both genitalia types resulting in higher libido than the other genders "Girls and Futas" as stated MorriganRae (see quote below)
"I assume Fiona could get Ashe pregnant "
Therefore, it sounds resonable that from this you would only need enough incidents where a Duplo has been acting in a criminal nature accenditally or deliberately for that to then send any remaining Duplo's "good or bad" (nature or intentions) to go into a sort of hiding.
It would then be plausable for any supportive families ; likely Ashe's mom and sister Rachel to also keep the secret that Ashe is a Duplo from the rest of the world
The other likely option would be that the mother may have done things to keep the fact that Ashe is a Duplo secret event from Rachel -- but this is very unlikely unless Rachel did not notice before she went away to College if I recall , but seeing at Ashe and Rachel seem like they where inseparable as kids unless the mother forced them to change outfits in different rooms it would seem unlikely that Rachel does not know that Ashe is Duplo. ( may have been mentioned directly or inferred indirectly in dialogue somewhere one way or another )
Thanks for the in-depth review.
In regards to the inconsistencies, I think you misunderstood the terminology of the sexes there (it is a bit confusing unfortunately). There are three sexes:
- Females: Around 50% of the population. Female genitalia.
- Mono futanari: Around 50% of the population. Male genitalia.
- Duplo futanari: Rare. They have a super high libido and thus have a nasty reputation. They have both male and female genitalia.
When people in this world talk about futas they technically mean both mono and duplo. But since most of them are mono that's what people just assume they are. So: Ashe is a duplo, all the other girls with bulges (Fiona, Cleo, Natasha, etc.) are mono (or at least they claim to be).
I may have commented on this before
if both Females and Futa , make up almost 100% of the population then how rare a Duplo is in the population depends on the population size.
in mathematics , as MorriganRae has not stated the exact percentage of the population for "Females and Futa " as take this to be a margin of error, for me , this would mean tha Duplo's should be about 1% of the population size.
this would then mean that even if a population of 10 billion existed a Duplo encountering another Duplo given the repuation they seem to have been given would it would make Duplo's be in the number of 100 million if they are 1% of the population size.
I would likely then expect Duplo's to be between 0.1 and 0.5 % of the population putting
- Females: at something like 49.75% to 49.95%
- Mono futanari: at something like 49.75% to 49.95%
