So, my sapient aliens are a TDSD (temperature dependant sexual determination) species, meaning hotter temperatures during gestation results in more female offspring. That being said, Korrinthia is a very warm planet, and therefore females outnumber males 10/1.

So, it has become standard practice in their society for females to be the dominant sex, and handle most of the roles which would (by earth's stereotypically patriarchal standards) typically be handled by the males; hunting, fighting, leading, etc. Meanwhile the males have taken on more of a defender/caretaker of the home & offspring role; they cook, clean, mend, maintain, and facilitate offspring.

Physiology, their culture views 'female' as the standard form of their species, and that 'male' is just a mutation of that base form which exists explicitly for the purpose of mating.

Now, with the exposition out of the way, let's get to the meat of the subject...

Due to the scarcity of males, females typically form "squads" -groups of between 4 &10 unrelated females whom share a bond of close friendship and often a mutual sexual attraction to one another.

But a squad is generally considered incomplete until they manage to draw a male into their polycule. Once they have a male the females will share the same sexuality with him that they share with one another, and he will be treated with very little difference than they do with any other member of the squad. (Outside of when they are seducing him into joining their squad, they dont really obsess or dote over him in particular, he's just there and participating.)

In fact, the only ways that he will be treated differently is in what roles he is allowed to fulfill when it comes to work, and only because the females are generally a little more protective of their male members due to the difficulty in attaining a their presence.

The reason I am asking if this is still a "harem" situation, is because the male is not the dominant factor in a squad, he has no particular authority and must comply with the squad leader just like every other member, he is literally just another member who has different body parts that facilitate the creation of offspring.

I checked the definition of a harem and it doesnt seem to fit most of the main parameters... So, what have I created here?

(Im genuinely curious what yalls opinion is! What do I even call this?)

The \"Act\"

A Female Forest Krii

A Male Forest Krii

The \"tools of the trade\" by phenotype.

The Phenotypes.

I have posted bits and pieces of the NSFW portion of my larger worldbuilding project about my aliens here and there on this sub, but never the whole thing. I figured since it was nearing completion that the time was right, and that this would allow me the chance to hear any final criticisms on it!

So, without further adieu, I present the "Sex and Reproduction" pages of Encyclopedia Korrinthia for critique and commentary. Fair warning, its kinda long...

~Introduction~

As a "mammal adjacent" sexually reproducing species, a lot of things should go without saying regarding this topic; but due to some very unusual cultural and physiological differences, this is has become a subject which the other species of the Ethereum can find rather confusing, and will thus require a bit more explanation.

An Outstanding Difference In Views:

Generally speaking, sex isn’t a very big deal to the Krii. It is neither considered to be the pinnacle of romantic expression, nor does it carry the usual social stigma most other cultures would place upon the act.

It also poses practically no risks between individuals, as their kind are not privy to permanent disease, and being a monestrous species the risk of bearing offspring only happens once every so often.

As a result, sex has become just another activity to pass the time, and is often viewed simply as a way to relax after a stressful day.

Physical intimacy is also rarely subject to the usual preferences which other species might hold when choosing whom to share it with. Gender isn't usually considered when coupling, neither is a distinction often made between romantic partners and friends; more often than not, it simply comes down to whom is available and "in the mood" to play.

A bit of Objectivity:

Unfortunately, it is often the opinion of those less educated on the subject that the Krii’s objectively unusual proclivities towards the subject of sex portrays them as having a promiscuous or even lecherous nature, but this is ostensible at best. For after my own time among them, I must say, that I find this subjective claim to have precious little to show in the way of actual credibility; as the average individual is, in my own opinion: "no more obsessed with sex than any member of any other Ethereum race." In fact, to any who have experienced this part of their culture first hand, it would not be divisive to say that your average Krii is by all outward appearances: "less driven by their sexual appetites than those others who would hold a more prudish outlook on the subject."

~Disproportionate Numbers~

Biology:

Krii are a warm blooded, live birthing, TDSD species. (Temperature Dependent Sexually Deterministic) -Meaning warmer temperatures during gestation typically produces more female offspring, while cooler temperatures typically produce more males, and Korrinthians generally do not prefer to be cold; therefore, there are usually far fewer males than females and it always has been this way, the current birth ratio being roughly one for every ten, but this number can vary across phenotypes, especially among the traditional peoples.

Male to Female birth ratios between Phenotypes:

(With average environmental temperatures.)

• Jungle- 1/11 (Avg jungle temp = 27°c)
• Mangrove- 1/12 (Avg Coastal temp = 29°c )
• Swamp- 1/9 (Avg Marshland temp = 24°c)
• Desert- 1/14 (Avg Arid temp = 36°c)
• Forest- 1/6 (Avg Forest temp = 12°c)
• Alpine- 1/4 (Avg Alpine temp = -20°c)
• Plains- 1/8 (Avg Grassland temp = 22°c)

Sociological Impact:

Many aspects of their social structure, coupled with their physical appearance and the scarcity of males has earned the Krii a nickname among the Milkyway Races; “Space lions." But these lions bow to no king; in this highly socialist society, majority rules, which means females are the dominant sex.

In the ancient past, tribes of females would clash with one another over access to males, who would have been captured and effectively held prisoner by the tribes to secure their bloodlines, in fact, the Krii lived like this all the way until the end of their bronze age when new laws finally made using males as currency illegal. Even then, they weren’t exactly free… for thousands of years before they met the other council races, Korrinthian males would endure censure and misandry from their female counterparts; unable to travel without an escort, paraded about like trophies in ridiculous and uncomfortable outfits, and forced to serve their clan’s every whim, without question or any safe place to voice their concerns.

Only in the vast peace of the Council’s Sanctuary, have the last thousand years seen the Korrinthian males gain more than just a semblance of autonomy. Now, with the support of the other Ethereum races, as well as the discovery of Xeno-Compatibility, many of the males from the modernist [Spacefaring Clans](Spacefaring Clans) have been more or less ‘set free’ to choose their own path, and have been taking some of their first steps into the wider galaxy. Though they may still face the residual misandry and objectification from the older females, new generations are steadily stemming the tide towards a more fair and equal empire, there has even been a modicum of change within the traditional clans, albeit a fair degree more limited; allowing males who are paired with a squad to leave the safety of the bastion trees and accompany their females on local missions.

Outward Appearances:

Despite the recent changes in their society, Korrinthian females are still markedly bold, confident, and aggressive, while the males tend to be comparatively more quiet, cautious, and reserved. This can be more than a little confusing for many of the Xenos they encounter, and in some instances has even generated a misconception among the less informed that there are no males, and that Krii can reproduce through parthenogenesis.

This illusion is partly due to their unisex clothing and androgynous faces, but can also be attributed to the male tendency to take a back seat in many situations involving extra-species interactions; as it has become so ingrained within the males to rely upon the strength of their counterparts that many have elected to retain their traditional support-roles within the clans.

~Female Physiology~

Monesterous:

Female Krii have a subtle heat-cycle which occurs randomly and can often see decades pass between conceptions; there have been many theories over the years as to what triggers Korrinthian ovulation, but as of yet the true stimuli remains an enigma. The seemingly random odds prompt most Krii to let fate decide when offspring happens, and since trying to keep track is akin to a game of Russian roulette, it will always be the individual’s emotional partner who claims the offspring as their own.

Dominance Hormones:

"Aside from being a TDSD species; Korrinthian females also become more likely to produce male offspring when they feel a sense of dominance."

When exalted into a seat of power, either through holding a position in the Officer and Matriarch ranks, or perhaps most famously: within the royal lineage to the Imperial Throne. Female Krii will demonstrate a tendency to produce excessive amounts of testosterone as a consequence of their position, resulting in a substantially higher ratio of male offspring than their un-ranked counterparts.

(TDSD- Temperature Dependent Sexual Determination. A biological phenomenon where experiencing extended durations of lower temperatures during gestation increases the likelihood of male offspring, meanwhile warmer temperatures typically produce a higher ratio of female offspring.)

-Anatomical Features-

(Physical features of female Krii which are a bit too provocative for the general lore.)

Dextrous Pelvic-Floor Muscles:

The reproductive organs of female Krii are incredibly tactile, capable of making adjustments to both width and depth in order to adapt to the size and shape of her partner since the genitalia of Korrinthian males is akin to a "Pandoras Toybox." This also allows her to perform stroking or swallowing motions at will, or automatically when receiving intense stimulation and during orgasm. These muscles can even close the vulva off completely, preventing unwanted intrusions or to retain the overflow of a recent deposit. (It is even rumored that these muscles allow Krii to have "motionless sex" and that they sometimes will even sleep while penetrated to take advantage of this feature.)

This dexterous network of latticed muscles is also the secret behind the Krii’s "Reciprocating orgasm" or "locking" function.

Specialized Vulva:

The vulva of a Krii is much thicker and more muscular than that of a human, and is shaped in such a way as to press the clitoris firmly against the shaft of her breeding partner in order to maximize her stimulation.

This part of the female anatomy is also used in sexual communication; becoming noticeably brighter in coloration as the individual approaches estrus, and even experiencing a degree of swelling during actual ovulation.

Dopamine Receptors:

Situated around the cervix of female Krii exists a ring of specialized chemical receptors which are designed to detect the presence of dopamine within seminal fluids. When directly exposed to fresh ejaculate these tissues trigger intense waves of pleasure sensations and a near-immediate orgasm response as a "reward mechanism" for successful copulation.

Cervical Pouch:

Situated between the cirvix and the pubic symphysis exists a small muscular pouch lined with papillae. This peculiar organ serves as a manually accessible storage area for excess ejaculate which did not make it through the cervix during copulation, and can be flexed at-will by the female to envelop the cervix to allow additional sperm to enter her uterus. This action also re-exposes her chemical receptors to the dopamine within his semen, allowing the female to experience casual deliberate orgasms for many hours after the male has departed, and exponentially increases her window for conception.

(Of course, when she is not in heat this is basically just pressing the "fun button" over and over.)

Perpetually Active Mammary Glands:

Krii are a group rearing species, and have therefore evolved for any female to be capable of feeding offspring at any time, even if the individual in question has not recently begotten any young themselves. This does not mean that females are in constant need of expression however, merely that they can produce milk if need be, and only if having recieved the proper stimulation.

It is also important to note: Krii have a number of dairy products; cheeses, creams, baked goods which contain milk as an ingredient, etc. Yet, try as you may, you will not find them using any dairy animals for these products; instead, there are individuals who are paid to hold specific diets in order to produce the milk for these confections. However, this does make such products more expensive than what one might find in other markets. The milk is also notably richer and sweeter than that of most other sapient beings and thus can be rather fattening, this is primarily due to their high fructose diets and adds a subtle "fruity" note to said confections.

Side Note: It is considered an extremely intimate gesture between individuals to provide sustenance directly from the body, if this is ever offered it would be safe to assume that the female in question is experiencing some very strong feelings.

Xeno-Compatability:

Due to the Crispr system which has embedded itself within the Korrinthian cellular matrix; female Krii have developed the capacity to reproduce with almost any sapient species which uses sexual reproduction.

The crispr system is programmed to protect the Korrinthian genome; meaning any DNA which does not match with its parameters gets "corrected". After an egg gets invaded by an alien sperm cell; the egg's DNA will naturally try to merge with the foreign genetic material, during this process the endemic crispr system will be scanning the merging chromosomes for malformation. Once it discovers an incompatible match; it will begin replacing the misalignments with the "correct" sequence to make the resulting whole as Korrinthian as possible, resulting in the offspring being of at least %99.8 Krii. So even if her partner is some kind of bipedal lizard man; the resulting offspring will always be a Krii of the same phenotype as the mother.

(The system is so precise in fact, that even if the father is a Jungle Krii and the mother is a Plains Krii; the offspring will be born as a Plains Krii.)

~Male Physiology~

-Anatomical Features-

Extended Seminal Network:

Male Krii possess a massive network of seminal vessels which are stored in the base of the tail, as well as a dense layer of subcutaneous tail-fat to fuel them, which to the delight of their partners; gives the surface of their tails a rather plush and springy texture, which they enjoy squeezing and fondling just about as much as human men enjoy breasts. However, it is the function of these attributes which grants male Krii the ability to mate multiple times consecutively, allowing them to physically keep up with the overblown female population.

It is particularly important to know that while a male Korrinthian has the physical ability to couple up to ten times in a row, that this is definitely not the norm. On average a breeding male will actually couple between two and three times a day, and often with breaks between days. Any more than this is only done for specific partners on request, special occasions such as pre-planned fun with groups, or if a mate is discovered to currently be in estrus; and he will usually take a couple days of rest to recover after such endeavors.

Likewise this excessive production of fluids is what facilities the male's participation in the "Reciprocating Orgasm" function.

Overproductive Testis:

Male Krii need to produce sperm at an extraordinary rate to keep up with the demands of their species' physiology, resulting in the fastest sperm maturation rate of any known vertebrate. With new cells being produced from start to finish within just a few days, this over productivity can actually cause a painful backup if not expressed regularly. Likewise, as male Krii are built to mate constantly, they tend to have an equally extreme appetite to fuel these activities; almost constantly snacking, a sexually active male Krii will consume almost twice the amount of calories and water than a female on average.

Dopamine-Laced Seminal Fluids:

It is actually normal for the semen of most any sexually reproducing species to contain dopamine in trace amounts, as this chemical directly coincides with sperm motility. However, when it comes to male Krii the presence of this chemical is dialed up to eleven; there is in-fact so much dopamine in Korrinthian semen that other beings often attest to having "strong sensations of euphoria" persisting for a noticeable duration after copulating with a male Krii.

Rather than coincidence, this is actually evolutionary feature of their species which is designed to work in tandem with the dopamine receptors located around the cervix of their females, generating a powerful chemical reward system for engaging in frequent breeding attempts.

Sensitive Sheaths:

Male Krii have subtle lips on the openings of their sheaths, which are capable of receiving fairly intense stimulation, rubbing against these lips will not only physically arouse him, but will also stimulate glands at the precipice of his sheath to start producing a viscous lubricant.

The urethra is also not connected to the male sexual organ in this species; appearing as a separate tube-like structure which lies along the base of the sheath with a subtle opening at the precipice, allowing for the the passage of waste fluids while reserving the male sexual organ for exclusively reproductive purposes.

The interior of a male's sheath is also unusually deep and demonstrates a high degree of elasticity, and is therefore sometimes used as an orifice for 'play' by more adventurous partners.

-Pandoras Toybox-

Hybrids:

The genital shapes of hybrids can vary wildly but are typically resemblant of the father's species, making statistical data inconsistent at best.

Advice for Interspecies explorers:

Needless to say, a male Krii can bring quite a variety of shapes and textures into the bedroom, and while they will often be more than willing to indulge your wildest alien fantasies, one should remain cautious; as the average Korrinthian male can be a lot to handle in terms of organ size and hip strength.

It is also important to note that male Krii will not be accustomed to the idea of "pulling out" or wearing prophylactics, but not to worry; Krii cannot carry or transmit xeno-pathogens due to lower than average body temperature and an artificially enhanced immune system. Also, it is only Female Krii who are xeno-compatable; so, despite their ostensibly extreme virility, -try as they may- a male Krii cannot get an alien pregnant.

~The "Reciprocating" Orgasm Function~

Female Krii have special chemically-sensitive nerve endings situated around the cervix, any indication of the presence of dopamine, such as what is found in the seminal fluid of their males, or when special chemically-laced lubricants are used, will trigger an immediate and intense orgasm response. In turn, the muscular movement from her “grand finale” will aggressively stimulate her partner to continue ejaculating, reactivating the chemical receptors with every surge, and triggering a cyclical response loop between the couple.

This reciprocating action can be very intense, and often a bit over stimulating; most couples are forced apart by the initial intensity, but a couple which can push through it will achieve an intense trance-like high from the dopamine overload; males will also experience a partial sensation of paralysis from this bizarre reflex; this is called “locking” and is a vestigial response from a bygone age which forces a male to stay inside and ejaculate continuously for several minutes, completely draining his reserves in a single session and greatly increasing the couples chances to conceive.

From the female perspective being able to “lock a male” is a mark of pride, not to mention the longest and most intense orgasm possible for both parties. Younger females who have not experienced this phenomenon tend to have a strong instinctual desire to engage the reflex but are usually apprehensive to ask because of rumors that the males do not actually enjoy it.

In truth, from the male perspective; letting himself get locked is the most intimate thing he can physically share with a partner. A male is very vulnerable in this trance-like state, and many are uncomfortable or even embarrassed by the near-feral state brought on by the reaction, so it is always better to ask before crossing that boundary in particular.

A female is also not necessary to cause this reaction, one merely needs to continue intense stimulation during and after orgasm until a second threshold is passed, the male will then "lock up" and begin a prolonged state of intense orgasm while clenching onto whatever can be grabbed until he is completely depleted.

*Edit (forgot this section)

Intercourse

Sex goes just about the same as it does with any species who reproduces in this manner; it can be light and casual, or it can be rough and passionate, it all depends upon what kind of energy they are willing to throw at it. However, when dealing with a Krii there will be some differences which will stand out pretty distinctly:

Firstly- when engaging with a female partner, it is important to remember that in her culture she is the dominant sex, which means she will usually dictate both rhythm and position, which in most cases means being on top.

Korrinthian females can also be a bit aggressive with their lovemaking, which often means biting; the usual target is around the collarbone, and while rarely more than a hard pinch, their teeth tend to be on the sharper side for most sapients, so broken skin could happen if you aren't protected by a layer of fur as they are.

With males things tend to be a bit more gentle, at least when it comes to the manhandling and biting. They do have very powerful hip muscles however, so its probably a good idea to make sure you are not too close to the headboard...

And though male Krii are generally considered the less dominant of the sexes, that doesn't inherently mean he prefers to be a bottom; many males still like to take charge and be on top, but oftentimes have trained themselves to wait for specific cues before indulging.

Another thing which often catches xeno sex-tourists off guard is the fact that there will be no "protection" when engaging with a Korrinthian bed-partner, and just in case any more clarification is needed: they do it bareback.

You wont even find such devices on Korrinthian worlds because there is no actual risk of disease among Krii, their body temperature is too low for most xeno-pathogens to survive, plus the radiation typically kills foreign microorganisms, and on top of all that their medicine is simply too effective.

As for pregnancy risk, yes, there is always a chance that one may get a female Krii pregnant, but those chances are incredibly low unless she is actively in heat; phantom ovulations can occur, but its statistically less than a 1% chance in most cases. And even if it did happen, bearing young is already such a rare occurrence for their kind that it would likely be cause for celebration rather than woe.

And with males its even simpler: male Krii are totally incapable of getting aliens pregnant, as sperm cells are too small to carry the Crispr gene-stabilizer which allows for xeno compatibility; so, despite their ostensibly extreme virility, their generous fluids are actually completely inert to anything that is not another Krii. (But be warned, their dopamine-laced semen can be rather addictive, and often leaves their "victims" in a chemically induced state of "euphoric bliss" which can last up to an hour after sex has concluded.)

Its also worth mentioning that despite the allure which all the bizarre shapes and textures a male Krii can bring into the bedroom, that they can also be kinda big for non-Krii, so just be sure to tell him to be gentle and to start off slowly...

Finally, do be aware; Krii are notoriously vocal during sex, they talk a lot, say some pretty naughty stuff, and are not quiet about it... they can also make some pretty strange noises; their language is accented by caterwauling consonants, and those noises dont come out of nowhere. Krii are full of sounds which do not sound like words, yet still carry meaning; they growl, chip, chuff, and churr, you may also hear chirps, yowls and trills, there is also moaning which should be rather familiar, but the volume can be rather startling at times. Just keep in mind: when you are among Krii; nobody is going to care that you are having sex... so let em' sing their hearts out; after all, it just means they are enjoying themselves.

(I'm gonna go ahead and leave out their courtship details, as that stuff is a bit more "cutesy" than NSFW, but if you want to get into that just check out the full section on my lore site: Sex & Reproduction (NSFW) - encyclopedia-korrinthia - Obsidian Publish

Anyway, that's that! & if you made it here then thanks for giving it a look! And I'd be glad to hear what ya think as well! ^.^
