Fires of the Futa Founders

If you have (let's say) 75% miscarriages and offspring which isn't able to reproduce, you still have 25% which is viable and able to reproduce.
So one "self-baby" might not be viable but statistically, there will be viable offspring if you give it enough tries.
And long term, the 25% will increase to almost or even exactly 100% as the genetic variation will decrease drastically.
See Selfing.

 

Inbreeding concerns aside, I'd be concerned about the character's pelvic area! Hip bones don't work that way, and dislocations there lead to life-threatening blood clots. None of those organs flex like accordions, even if you have a collagen disorder. If your futa character's penis is right around the perineum, you might be able to get away with just (just) some pelvic floor damage and a smooshed-up uterus. Perhaps a smooshed prostate, too? That might make carrying a child impractical, let alone a repopulation effort.

 

I was figuring ka would use artificial insemination.

Delicately put XD
Given that its perfectly possible to make a baby without penetration taking place I've got to assume that if a futa can impregnate themselves then they inevitably will.

 

Not inevitably, it just takes self-control, such as only getting off via your cock inside another person's body...

(Blowjob, anal, or vaginal: never masturbation, handjobs, or tit-fucks.)

EDIT: (Unless perhaps you're assuming that any form of masturbation will cause seminal emissions, as both organs are connected to the brain, in which case it's still not inevitable as they only have to do it lying face down in such a way that the semen is collected in a separate container and be careful about cleaning up.)

 

Vaginas and anuses aren't vacuum cleaners...
And don't forget: Never have wet dreams.

 

Firstly, spermicidal lubricant is a thing, but you're right it could be an issue.

Secondly: did you know that I've never had a wet dream in my life? If you masturbate responsibly it just doesn't happen... (See my edit to the previous post.)

 

Alternatively the male and female parts might not be fertile at the same time, cycling back and forth over the course of a month and making self-impregnation very rare.

 

but you go straight to hell
(Some say that being a teenager is hell, so that's not only applicable in a religious sense)

 

Hell is other people, so I'm not that worried. I'll organize a D&D game.

 

Bad news, in hell they'll only let you play F.A.T.A.L.

 

Always wanted to learn that system.

 

@ms hammer critic has a point, though. If a futanari person has both full reproductive systems, those internal organs all have to go somewhere. (The male bits aren’t all external, for instance. ) Even if we stipulate that there’s an internal configuration that makes conception possible and a pregnancy viable, it seems likely that there’d be an increased rate of pregnancy and childbirth complications involved. If our Adameve really is all alone, the story should probably touch on the potential dangers, especially if they’re going to bear enough children to create a viable colony’s first generation given the already mentioned genetic issues.

Maybe some kind of external incubator system would make the most sense. Say, if the technology couldn’t support incubation for the first few weeks but could then extract and incubate automatically for the rest of the term.

(I realize that might step away from the kink and might go against the story’s requirements—there’s other potential solutions of course.)

 

Oh yeah. Hermaphroditic species do still skew towards reproducing with mates, and will tend to have some protections in place against accidental self-fertilization. That’s generalizing wildly, of course. Your window for getting a human pregnant is pretty short regardless. That’s without the stress this kind of situation will cause, throwing off twice as many cycles!

Pregnancy without intercourse is certainly viable and happens more often than many realize. I don’t mean to minimize that.

If the character’s crash-landed disastrously, though, I guess my other question is how many tools the character has available to them? I would worry about hygiene on an alien world. If you don’t have a sterile way to get the semen into place, what are you introducing into the vagina? Would they end up screwing up vaginal pH or cervical mucus, making things moot? Could they be rubbing pathogens or random unknown trace elements into themselves, potentially endangering the whole operation (if not the parent)?

If there’s enough of a clean lab to use an incubator like @Rubicon suggests, then everything else can be worked back to. Sexy nitrile gloves. Refrigerate some semen in a clean vial. Chart a couple of menstrual cycles while growing potatoes. Journals and charts! Venn diagrams can look like boobs.

 

Um... what's the difference between an unwashed finger and an unwashed cock?
Generations of humans have survived bad environmental conditions and still survived.

Besides, living on another planet makes it pretty unlikely to suffer from pathogens as they are most likely not compatible.
So domestic bacterias would more likely eat your clothes or the metal of your housing than killing you.

 

Sugars are sugars gene.sis. With the exception of the whole 'right/left' split, which is far less important to bacteria, things like yeasts and so on can survive just fine in some very unusual conditions. However, for that exact reason, I don't foresee this becoming an issue as humans and other sapients would be smart enough to largely avoid planets with an existing biosphere unless unutterably extensive testing by robotic probes, on the order of a thousand years or more, showed them to be safe enough for colonization, the chances of which are vanishingly small. More likely we would Terraform life-less, (but otherwise mostly suitable,) planets, such as Mars.

Furthermore, there are many bacteria that in their native environment are harmless, such as polio, which is integral to soil creation and maintenance the world over, but if they get inside a human body they wreak untold havoc.

 

Pathogens would still be an issue based on the stuff you brought with you, depending on the crash. If there's a ton of dead bodies lying around, for a while bacteria's going to have itself a field day -- and to a degree anyone on another planet has to literally incubate bacterias if they're going to survive. We need our intestinal flora among other things. That's also assuming that absolutely no vermin came with you on your ship -- and anywhere humanity goes, rodents and insects and other things go along with. Heck -- if you're introducing agriculture to this new world (and how will you survive if you don't?) you're introducing tons of bacteria and other things into the environment by necessity.

But in this case, I'd be more worried about the 'trace elements' @ms.hammercritic mentioned. New environments and atmospheres means new conditions. It doesn't take that much to screw up your uterus's pH balance. And yeah -- generations of humans have survived bad environmental conditions in the environment we evolved in and survived... but a futanari's going to have different issues, this isn't the environment humans evolved in, and those 'generations of humans' are as much a numbers game as anything else. A lot of people have miscarriages or worse because of contaminants or tons of other reasons -- there are just more who have successful pregnancies. Since we're assuming that Adameve wants to self-breed and have children, it becomes a fertility treatment style issue. You want conditions as perfect as you can get them, since problems with the pregnancy are at the very least millions of miles away from the nearest OB/GYN, not counting automated medical systems.

None of which makes the story unfeasible. Honestly, it makes it more interesting, to me. Hammer C mentioned 'growing potatoes,' and that's not a bad template. Think The Martian, but with extra bonus insemination and gestation. (In fact, Nemo had specifically invoked The Martian in his original scenario.) Adameve (all right, Kae, in his original description) has made the conscious decision to populate this world on their own. Overcoming the obstacles to both self-fertilization and then carrying successfully to term and not dying along the way... and then doing it again, probably several times? That's the first third of the story at least, honestly. (Though ultimately they'd likely come up with a decent workflow in the process.)

 

(High five to Nemo! Double-posting for the win!)

 

That's tongue in cheek, isn't it?
While a single human might be smart, humankind isn't known for thoroughly examining a situation before jumping right into it.

Sure, bringing bacterias with you is a surely a thing, though you would just leave behind a large share of diseases.

A lot of (most?) animal diseases aren't communicable to humans and while humans at least have a common ancestor, this won't be the case on another planet with an existing biosphere. So they might not even have a DNA or RNA but some other fancy way of storing genetic information — if even necessary.
Though on the other hand, you might encounter some kind of alien cold which would skin humans alive.

Let's say a woman gives gets pregnant 13 times during her life. Assuming one-third of miscarriages and another third dying because of infant mortality, there are still about 6 children left. For humans, that would be tripling, but for a futanari, it would be sextupling. (That might only apply to a young species of futanari before natural selection decreased high fertility)
That said, just the knowledge of hygiene would help to reduce both, miscarriages and infant mortality.

But for sure, one generation of bad luck and you vanish from not-earth.
