Hey Hello Hi

Male Alpha

🌕 Let's start with our boys here.

🌕 Honestly they're pretty straightforward! There's not too many crazy anatomy changes here. They function pretty much the same as irl amab anatomy does.

🌕 They have a penis and external testes

🌕 They have a prostrate that can be stimulated via anal penetration

🌕 Male alphas tend to be on the bigger side concerning length/girth but this varies from person to person

🌕 Now, the defining characteristic of a male alpha is their knot. Only alphas have a knot!

🌕 The knot is soft tissue that expands during orgasm. This "locks" the penis into the vagina in order to facilitate conception. In simple terms, sperm stuck inside better change pregananant

🌕 The knot typically stays expanded for about 20min after orgasm, but this can vary. Any longer than an hour though, can be cause for concern

🌕 The male alpha usually has a larger knot than a female alpha and experiences higher chances of successfully "tying" (tying here meaning the knot actually gets stuck in the receiver)

🌕 An alpha can knot outside of rut, but these knots may be smaller or not fully expanded since they're lacking the overproduction of hormones that rut creates

🌕 A deflated knot is still visible as a ring of much softer tissue than the rest of the shaft

Female Alpha

🌕 oh boy, oh god, mother mary save us all

🌕 This one was so HARD to figure out fr... let me get into this

🌕 I've always liked the idea of a female alpha having a hidden penis best. One that's concealed where the clit ought to be but expands and pops out during rut or when aroused. I like this one best bc I'm not a super big fan of the anatomy set up of having a vulva and dick and balls all at once, and anatomically I never understood like... the concept of the clit swells a lil and thats the knot bc... penetrate how?? I also just don't like pregnant female alphas much! To me alphas impregnate only not carry

🌕 So hidden penis was my favorite option !

🌕 But once I started drawing out the diagram I immediately had problems placing the sheathed penis inside the body

🌕 My biggest issues were the bladder and pubic bone. The bladder I can move around easy enough, especially since female and male anatomy have it in slightly different positions anyway

🌕 But what was fucking me up was that damn bone

🌕 If we want to replace the clit with a penis the penis is going to need to run straight through that bone. The pubic bone in female anatomy sits right above the clit basically. In male anatomy its a tad higher up but even moving it up it would still be in the way of the penis

🌕 I could continue to move the bone or do away with it but then we compromise the human shape of the female alpha. The rest of the dynamics would look human in the hips and pelvis but female alpha she'd be.. little fucked up. Not to mention I'm sure there's some other wild medical consequence of removing or moving the pubic bone that I'm not aware of

🌕 So... we can't put the sheathed penis exactly where the clit is

🌕 I could put it where the vagina is, but then that eliminates the vagina entirely and makes female alphas unable to have penetrative sex and tbh I'm not into that give her a gspot yk?

🌕 I could move the urethra around, like push it forward towards the clit even more and push the vaginal opening backwards, or even combine the vagina and anus like the male omega but I wasn't a fan of that either. It makes her feel to male omega-y and less unique to me

🌕 Furthermore like... vaginas are low. Like lower than u think, clits are a little lower too. And penises are so high! So.. having a penis come out so low between your legs wouldn't that make penetrating kinda hard unless you had a crazy long horse cock or smth.

🌕 So I ended up keeping the penis sheathed like I wanted, but I moved it up

🌕 The penis head is a little above where a clit would sit but I still removed the clit from her anatomy

🌕 To avoid the bone I had to put the penis above it. This isn't super crazy since the vans deferens also comes down over the bone, but it is a little awkward because this isn't a little tube this is a PENIS. This is a whole long cord of tissue and blood vessels here and I'm not giving her a small flat cock to compensate she doesn't deserve that

🌕 So, her muscle, fat, skin, and what have you is gonna have to push out to make room for the penis sitting above the bone.

🌕 Insert female alpha sheath bulge >:))

🌕 tbh I think giving her a bit of a bump is pretty hot so I'm satisfied!

🌕 However bc its sitting right over a bone any pressure applied to it is going to be uncomfortable or even painful for her

🌕 So... ig if you wanna kick a female alpha in the nuts aim for her sheath fr

🌕 So then I was good for awhile, I had placed the penis in the body in a way that satisfied me and kept the vagina intact

🌕 But okay now the penis has to come out

🌕 The female alpha cock still sits lower than the male one, so we have to do a little more bending to get it to flip up in proper penis formation

🌕 No problem, I'll just give the female a longer base after the knot and said base will be way more bendy than a real penis np np

🌕 Okay but... if we have a noodle base how is the erection staying erect and not just becoming a top heavy string of stuck blood that flops tf over

🌕 Insert what I did with the labia

🌕 I want female alphas to enjoy vaginal sex if they want to mostly for kinky reasons yk but its my world so!

🌕 But this means that I don't really wanna touch the labia around the vagina, they should still get looser during arousal they should still be fun to play with yada yada yada

🌕 But the penis needs something to lock it upright. So I split the labia into even more parts.

🌕 On irl afab anatomy theres the inner and outer labia and that's that. On the female alpha tho I had to get creative. I gave her her inner and outer labia that would function normally

🌕 Then I gave her another set around the exit of her sheath. I called them! The penile labia for lack of creativity and anatomical knowledge! Unlike the outer and inner labia around the vagina, these ones stiffen and lock up during arousal after the penis has been unleashed. This keeps it out and helps it stand!

🌕 I also gave her a middle labia. This is an extremely tough piece of muscle that separates her upper and lower sets of lips. The middle labia supports our bendy base even more and tends to get engorged and may even expand a little to support the weight of the cock and knot

🌕 This isn't fool proof by ANY means and I'm sure ppl who know anatomy better than me have a million issues rn but yk what? This makes sense to me and took me awhile to figure it out fr so I'm content

🌕 Now... I gave her a uterus-like structure and still called it "uterus" for lack of better term. this is not a functioning uterus so female alphas cannot conceive

🌕 But in this model I have this uterus act more like a muscle that helps push the penis out of the sheath. Believable? Idk but its chill with me

🌕 The female knot is generally a littler smaller than the male knot because it's gotta fit in the body

🌕 The knot here doesn't even begin to expand until the penis is unsheathed, whereas in males it may puff up slightly on initial arousal

🌕 Since I did not give her balls, her testes are inside the body where the ovaries would typically be

🌕 insert the part where I tell you alpha sperm does not need to be cool. It can survive higher temperatures which also makes sense considering omegas practically have heat strokes during heat, the sperm would need to be a little tougher.

🌕 But then why do males have balls? I got u fam ! Bc while they can survive in warmer temperatures that does not mean they thrive there. The healthiest swimmers are still kept a little cooler. Female alphas may be less fertile even because of this which could be some fun plot points bc i love female alphas pls write them more

🌕 That was so LONG but I think that's it for her

Male Beta

🌙 The male beta doesn't really have anything super atypical from irl amab bodies.

🌙 The penis of a beta tends to be a lil smaller than an alpha's but bigger than an omegas, but again this isn't always the case!

🌙 We do have a prostate for fun anal times if desired

🌙 Beta sperm is not as heat resistant as alpha sperm. They can impregnate other betas just fine but may struggle with an omega in heat. It's suggested that b/o couples try conceiving outside of heat with the help of fertility experts :>

🌙 Male betas cannot conceive, they have no uterus or vagina

🌙 Betas do not knot!

Female Beta

🌙 Again, not a lot of differences to talk about here, typical afab anatomy

🌙 It is worth noting that in my verse I am not giving female betas periods bc thats mean

🌙 For this reason their endometrium is thinner than ours so the body can reabsorb it without a true heat easier

🌙 I'll also say that beta eggs are just built different for this thinner endometrium

🌙 usually you need a certain thickness for the egg to embed properly to the uterine wall, but imma say that for whatever reason beta eggs are totally chill with a thin lining. They have a better grip or smth ig!

🌙 This allows my girls to get pregnant without an extra added issue due to my silly anatomy choices

🌙 It also makes her different from the female omega which I'll talk about later :))

Male Omega

🌑 Okay ya'll get ready for shitshow number two

🌑 actually the male omega wasn't as bad to figure out mostly bc I stole the idea of the epivagina from the author I linked above the cut!!

🌑 I'll sum up if you don't want to read through the link (you should tho it's really interesting stuff you might wanna use in ur own verse!)

🌑 So like the female alpha there are depictions I don't like when it comes to the male omega. I don't like them not having a uterus and just being... a guy? Like having nothing about them that makes them different than a male beta. Also, like how I said I don't like pregnant alphas, I don't like omegas that can impregnate.

🌑 I'm also not a fan of not giving them a penis and having them only have a vagina and uterus. What makes the two omega genders different then? Breasts? Not a fan tbh considering I like my male omegas to breastfeed with their lil pregnancy boobies (cancer in venus I like boobies and lactation not sorry)

🌑 Basically I want my mpreg and I want my penis too

🌑 So, like the female alpha, we have to give them both parts.

🌑 Since there's not a ton of room between the balls and the anus (the taint is only so big yall) I'm not a fan of just giving them a vulva here

🌑 I'm also not a big fan of the birth canal that develops from the taint when pregnant just bc it doesn't make sense to me that the body just forms and unforms a hole that they have to push out a baby the size of a small melon through. Like in that case pregnancy must be excruciatingly painful on top of pregnancy already being painful and hard

🌑 So... butt babies. Except not quite

🌑 The popular option is the cloaca but... I have issues with that too

🌑 If you read the chapter on male omegas on the ao3 link you can see why. A short cloaca definitely results in poop in the vagina. I don't think I need to explain why poop in the vagina is like the worst thing. As the author points out it also makes it difficult for fun oral time just bc the amount of infections you can get from... constant ass licking/fucking especially bc I haven't seen any male omegas telling their alphas omg wait i need to shower, shit, and have an enema first

🌑 The long cloaca can work ig but then the penis never enters the vagina and thats just not fun. The male omega would never be able to have vaginal sex fr :((

🌑 So I'm going with what the author made up! The epivagina!

🌑 The epivagina is a strong valve-like muscle kinda like the middle labia in alpha females.

🌑 During non horny times the epivagina remains positioned in a way that closes off the vaginal opening. No penetration without literal tearing can take place with it closed. The anus is open and free for poop!

🌑 During heat and arousal the epivagina switches the other way opening the vagina and closing the anus so the opposite is true

🌑 You do not have to be in heat for the vagina to open btw! Just turned on

🌑 During birth we can just assume the sphincters and muscles around this anus and vagina were built for stretching, though it might be recommend for male omegas to anal train a bit to get all our muscles ready for it (there are literally butt plugs the size of a child's head so we can train out asses a lil)

🌑 Now the drawback to this would be that... you cannot have anal with a male omega if he's turned on. Tbh that's okay with me since i'm not really into anal anyway! If it's not okay with u then.. idk change it to fit ur kink babe im not stopping u

🌑 It also kinda acts as a rape defense too in a way.... like a duck if we're not turned on good luck entering the vagina. ofc... the exception to this is heat in heat it's p much always open unless we need to shit rn so ig vaginal rape protection in heat isn't a thing but it's neat outside of heat

🌑 Male omegas do produce very small amounts of sperm but they're such sad little boys it's basically impossible to get pregnant from them. Most of them have clear orgasms if they come from their cocks at all.

🌑 I did raise their balls a bit back into the body. We're still descended but not... exactly the whole way if that makes sense. Our sperm just isn't as cool this way and it's not heat resistant fr!

🌑 Bc omegas get so hot during their heats this can also decrease or fully kill off any remaining sperm production.

🌑 Technically this way you can still get pregnant by a male omega if you're a female beta/omega but.... bc its my verse and I don't really want that I'm gonna say it happens like once in a century it is not really a thing

🌑 The penis here is smaller than anyone else's, but not as small as you'd think. I'm not going the whole micropenis route with them you can still be satisfied through penetration with my male omegas!

🌑 Like the author, I also like the concept of giving them a prostate and an internal clit >:))

🌑 no real reason other than 3 ways for my boys to orgasm and I like it

Female Omega

🌑 Pretty similar to the female beta, not too much difference from irl afab anatomy

🌑 The biggest difference between a female beta and female omega are:

🌑 Slick production (beta's do not produce slick)

🌑 The endometrium

🌑 I gave my beta's a thinner one so their bodies can absorb it and we can avoid menstruation!

🌑 Well in female omegas the endometrium is thicker, about the same as the average one irl or maybe even a little thicker than that.

🌑 Her eggs just aren't as good as gripping just like irl fr, so we need a lot of cushion for them

🌑 especially since female omegas tend to release more than one egg a cycle (2-4 is normal) so if we're all embedding we need more room to do it

🌑 A female omega also can reabsorb her endometrium no worries I am not giving her a period either

🌑 Instead I'm going to say that heat has 3 phases. Pre heat where we get ready for ovulation that lasts about 3-4 days, heat heat which lasts about 1-2 days or less. This is when we are fertile we need to get pregnant NOW, and then post heat which lasts about 3 days where our body temperature is still extremely high and we're still horny and feverous but the egg has passed alas. Its during post heat that we reabsorb and break down the endometrium. Sometimes we might see a little blood a lil spotting yk, but for the most part our heat stroke helps us absorb it idc if that's unreasonable its what imma say

🌑 The term heat usually includes heat and post heat but not pre heat (I mean you get off work for heat and post heat and we use the term heat as a collective to include that 5 or so days but this doesn't include the pre heat) but i'll do a different post for heats later !
