23 days ago, I made a post here regarding "Homo vigilans" an alternate version of the human species that fills the place of humanity in my world-building projects.

As detailed in the post, Homo vigilans are illogically gendered hermaphrodites wherein they have both a male and female sex but the difference between their sexes is purely aesthetic and both H.v men and women are capable of becoming pregnant and giving birth.

Someone in the comments informed me that the reproductive system of H.v didn't make a lot of sense so I've spent the past week or so re-developing it.

I wanted some opinions on the new concept I've come up with.

-

To start, H.v have an estrus cycle instead of a menstrual cycle and this means that their bodies re-absorb discarded uterine lining instead of bleeding it out.

Now, an estrus cycle necessitates a "heat cycle". I'll admit that the concept of humans in traditional heat ( insatiably horny for a specific period of time ) is hot but it doesn't work for the stories I want to write.

What I came up with is that H.v heats abide by a system of "silent and irregular poly-estrus". This means that 1. H.v go into heat multiple times a year but 2. Their heats are "silent" and cause no noticeable physical or emotional changes and 3. The time between their heats can fluctuate wildly with individualized environmental and metabolic changes.

This means that H.v cannot reliably track their heats so un-planned pregnancies from random hook-up's with unprotected or poorly protected intercourse are very possible. Some research I did suggests that H.v's irregular and silent heat cycles would need to occur every 60-90 days or 4-6 times a year for them to have population growth comparable to real humans.

-

In addition to this, H.v men almost always suffer from "secondary infertility" after becoming pregnant and giving birth once and H.v females have a naturally low sperm count. As a result, H.v have a historical preference for male + female pairings and they did develop a concept of homophobia but it's much weaker against societal reform compared to real world homophobia.

So, what do you think? Does this make sense or does it need more improvement?

Repost

There was a communication error in the previous post and people's comments were not what I was looking for. I reworded the post to make my intentions more clear.

Recently, I have been working on the main characters of my primary world-building project and more specifically, their NSFW aspects.

I'd like to know about your world's main characters? Do they possess any major attributes that are NSFW as your worlds are and if so, what are these attributes?

For a little while now, I have been dealing with a weird issue in the setting of my secondary world-building project ( "Project Vigilant" or P.V ) wherein I have several characters who I want to look pregnant but they aren't actually pregnant because the presence of a baby would complicate their storylines.

Basically, I've been trying to come up with a way to explain characters who look like they are pregnant and seemingly permanently so but aren't and I think I may have come up with an idea that I'd like opinions on.

Recently, I learned that amniotic fluid has a lot of medicinal benefits but for reasons that should be obvious, it's an absolute bitch to harvest and thus it is very difficult to take advantage of.

I had an idea that my falsely perma-preg human characters could be part of a subset of humans who, via an exotic mutation, are able to produce amniotic fluid without being pregnant.

At a certain age, these humans start experiencing automatic pseudo-pregnancies wherein their uteruses fill up with amniotic fluid but there is no baby. The amount of a.f they produce is indefinite so their bellies will grow to whatever the maximum possible size is for them and whenever they get uncomfortable, they simply go to a hospital to get the fluid drained but their uteruses will start to refill shortly thereafter.

Medical professionals like these people because they are essentially a walking source of pure, un-contaminated and relatively easy-to-harvest amniotic fluid which can be used in a wide variety of medicinal applications. They live normal lives and for them, getting their excess a.f drained is like a plasma donation + relief.

What do you think about this?
