/sci/ - Science & Math

Yeah, it's called flushing the body of old blood and materials that aren't being used to sustain life at the moment.

If you don't like it, stick to the cock.

lulz the vagina CAN be contracted. You just made it obvious that you've never made a girl cum.

How the fuck should i know something about women?!

Uncomfortable sensations providing useful feedback on the individual - Why are you getting these uncomfortable periods when you should be pregnant right now?

>>1804938

Lol, no. It's just flushing out preparations.

A period is FAR LESS uncomfortable than carrying a child to term.

>>1804936

Lol, this. OP is a giant faggot.

>>1804933
So then by your logic I guess it's not necessity to control our bowels ether.

>>1804936
I think he's referring to the fact that you can't just "hold in" your period.

Or... CAN YOU?

>>1804958
>implying shit is a life sustaining material instead of a waste product.

>>1804960

Who would want to?

>>1804921
My guess is that the reduced seasonality in mating is what leads to a constantly open vagina. In several lemur species which mate in at very specific and regular intervals their vagina seals during non reproductive seasons.

>Super mega ultra virgins detected

The vagina only contracts during organism and the delivering of a baby. If woman would voluntarily contract there would be no need for tampons you fucking morons.

>>1804962
what? no

Go back and reread the posts

>>1804969

that is hilarious. I'm not a virgin, and I'm a woman, who is contracting her vagina as we speak. It's called kegals, and yes, a woman DOES have elective control over the muscles in there.

Just like how guys can make their penises "dance". It's muscle contraction.

You just keep digging yourself deeper and deeper.

holy fuck op is retarded

>>1804969

>implying a contraction would help you hold anything in

>>1804979
what the fuck am I looking at

Monthly menstruation is a modern phenomenon. In old times woman would get pregnant as soon as she becomes fertile so most of the fertile life she would spend pregnant or breastfeeding.

Since today people live longer and the mortality is ridiculous low there is no need to get that many childs and the result is all those tampoons.

>>1804986
>You just keep digging yourself deeper and deeper.
WHY DO ALL GIRLS SAY THIS

>>1804921
Just out of curiosity, what's that giant organ next to the vagina? It's as large as a stomach, looks like a big gut, and isn't attached to the anus. what the--

>>1804969
HOLY SHIT fucking idiot. I'm a girl. Look at my name. I can contract my vagina whenever the fuck I want; no I can't "hold in my period" just like you can't "hold in childbirth"

>>1804991
NO YOU

>>1804986
So I guess you never use tampons and can squrt blood out your cooch like a water gun right?
Yeah whatever tits or GTFO

fixed that for ya

>>1805028

You have really fucked up ideas on how the female body works.

Open a basic biology book. It will prove everything that you think WRONG.

>>1805008

It is the urinary bladder. It's smaller than the uterus because the uterus has no need to take up much space unless it's carrying a fetus.

>>1805036 look it up
heck no. i looked up dracula on wikipedia and got my mind fucked by what impalement means, that's enough for a day

>>1805032
OP here im actually a girl and you're full of shit

Ether that or all your gunt fat is keeping your vagina clamped shut.

OP is a 12 year old boy.

>>1805045 bladder
Yes, it must be the bladder, now I see it as well.

>>1805040
And you have no fucking clue how female body works at all. Why is it so hard to rap your mind around the fact that the vagina can not open and close at will? What kind of anatomy do you think females have?!?!

>>1805056

>thinks this is /b/

>>1805055
show pics of your contracting pussy and then stfu and go back to kitchen, bitch

>>1805047
A girl who thinks you can't contract your vag? Uhhh you know, you can't literally hold in your period for a week, just like you can't hold in your pee for a week. But you can hold in those random blood clot thingys- not to be gross but I mean that happens. So yeah, if you're a girl you know that you can contract your fucking vagina. Don't be retarded and say you're a girl if you're not. Fucking faggot.

Now imagine if they had teeth =O

>>1805067

Okay, you've misinterpreted my post. I'm saying it CAN'T open and close at will, but the muscles DO contract, and it can be done at will.

YOU are the one who seems to think that a vagina = nerf squirt gun.

Open that biology book. Go on, I dare you. You're not afraid of being wrong, are you?

Virgin.

>>1804921

"evolutionary benefit"

Doubtful; but I doubt there's any serious evolutionary negative to having it that way either.

>>1805071

Dude, you have google, look it up yourself, faggot.

And make your own fucking sandwich. I'm not here to be anybody's fucking mother.

>>1805069
>thinks this isn't /b/

Sorry but if /sci/ is full of the same 12 year old /b/tards and not a smart person in the bunch. That is quite obvious by the stupid people posting ITT who claim to be vaginal expects meanwhile they probably think all woman pee out their vaginas huuuuuurrrrrrrr

>>1805006
THIS!!!

you sir are not a gentleman

Oh my god.

Get out of grade school, and then come back and try to have a conversation with the grownups, k?

ITT: too good for high school biology

>>1805076

I have never experienced this phenomena. Care to explain how you hold in your clots?

>>1805076
>Uhhh you know, you can't literally hold in your period for a week, just like you can't hold in your pee for a week. But you can hold in those random blood clot thingys- not to be gross but I mean that happens. So yeah, if you're a girl you know that you can contract your fucking vagina.

Oh god if you were really a girl you would know how fucking stupid you sound right now. I just went and asked my mom if she's withholding some kind of "secret vagina blood holding technique" from me and she said that was the stupidest thing she ever heard.

Now there are two woman who think you're a fucking tard.

>>1805092
lol @newfag. And actually I'm sure some people are this retarded and not just trolls. Either way I don't mind responding to it.

>>1805113

Them being retarded isn't so bad; it's how PROUD they are to be so damn ignorant that gets to me.

Thank you for spoiling my dinner for me /sci/.

Ugh...

>>1805111

Well, if you describe it as "secret vagina blood holding technique" of course your mother would think you were retarded.

I'm betting she's also wishing she had swallowed instead.

>>1804986

hehehe she said Penis Dance

>>1805124

>expecting not to be grossed out on the internet

>>1805111
Uuh that's because it's secret. Lol no I mean you really can't hold in the blood of course, I was talking about if there's like a bunch at once that built up when you were sitting or something, you can kinda feel it move back if you contract. But yeah it's GONNA come out, so your vag isn't so good about that like your urethra or anything. The point is, you CAN contract it, but like I said, you can't hold in your period blood throughout the week and avoid a tampon lol. The way you said that to your mom is fucking hilarious.

>>1805126

It's what they dooooooo!

I don't know how else to describe the movements a cock makes when a man contracts those muscles, but yes, it does look like a happy little dance :D

>>1805080

we should archive it

This thread saddens me. EVEN FEMALES in this thread are completely fucking retarded. Well or just that one who asked her mom for a secret blood holding technique. At least male virgins have an excuse not to know shit about vaginas.

Stay classy ladies

Dear Diary:
Today, I learned about vaginas.
-Samefag

wait, does this mean that all humans do not have identical musculature!??! DEAR GOD!

>A persistent cloaca is a complex anorectal and genitourinary malformation, in which the rectum, vagina, and urinary tract meet and fuse, creating a cloaca, a single common channel.

>Diagnosis of a female with cloaca should be suspected in a female born with an imperforate anus and small looking genitalia. The diagnosis can be made clinically. Failure to identify a cloaca as being present in a newborn may be dangerous as more than 90% have associated urological problems. The goal for treatment of a female born with cloaca is to achieve bowel control, urinary control, and sexual function, which includes menstruation, intercourse, and possibly pregnancy. Cloacas probably occur in 1 in 20,000 live births.

The red part is the vaginal canal, it ends in the cervex and uterus

>>1805254

>>1805248
All humans have pelvic floor muscles. It's what keeps your guts from spilling to the ground every time you stand up. It also just so happens to be where the anus, urethra, and respective sex organs exit the body/are accessed. Men and women both can do pelvic floor exercises. Women typically do them after childbirth to regain control, and both elderly men and women do them so maybe they won't have to use diapers as much. Whenever men urinate, orgasm, or do the "penis dance," they are contracting the pelvic floor. Women have the same muscle function but do not have the same saluting capabilities when they do it.

Similar functions but with slight anatomical differences.

Oh, and while we're on the subject of squirt guns... http://www.youtube.com/watch?v=YdAIt4MgnHc

The vagina does contract, not fully, but when you make a girl cum hard, it will om nom nom on your wee wee

Obviously you microdicked engineers have never brought a girl to orgasm, no big suprise there.

>>1804921
SERIOUSLY, whoever drew that picture?

>>1805316
No, they're all engineers which means they're all gay.

being unfuckable by the opposite sex doesn't make you gay.

Gay people get laid all the time, that's why they all have AIDS.

I haven't looked at the stats, but I would guess that the prevalence of STDs in engineer majors at college is about 0.00 percent.

>>1805137

Dude, chill. You really need to work on your reading comprehension before you post.

>>1805286

You are a genius compared to other posters in this thread. I salute you.

>>1805346
yo, gay engineer major here. caught syphillis a few months ago. pretty sure those stats are unpublished

>>1805346

Don't you know 45% of all statistics are just made up?

And thus today, /sci/ became /sci/b/

>>1805355

as a faggot, would you say faggots are capable of a stable relationship? I find that any stereotypical behavior in one gender is exaggerated in homosexuals. All men want to fuck, so fags all want to fuck, 24 hours a day, even when they are dying of AIDS, and mad with syphillis.

Dykes on the otherhand have the most stable relationships because they are nurturing and caring to an exaggerated level.

What say you, fudgepacker?

probably because its easier for men to penetrate that way for men.

evolution.

>>1805383

as much as your syphallis is burning when you pee?

>>1805399

Lolwut?

There would still be an opening to penetrate, whether it contracts or not.

Which it does.

>>1805402

As much as your spelling is burning my eyes.

How hard is it to spell check?

IT WAS GOD's PLAN SINCE THE BEGINING!

>>1805370
lol humans are not inherently monogamous. in fact, very few species of primates only have one sexual partner in their lifetime. why do you think the majority of marriages end in divorce? how come both men and women in "monogamous" relationships cheat? it's not in our nature to be monogamous. it's just an unrealistic expectation created by society at a time when science was punishable by torture and death. gay, straight, lesbian, transhuman? doesn't matter one bit. and women are less likely to proclaim their sexual encounters because society (here we go with the unrealistic expectations again) will call them sluts, whores, and whatever else we can think of. they are still just as capable as men. but what do humans enjoy more than sex? why, banding together and throwing rocks at the outcasts, of course!

>>1805416

Marry me?

Monogamy only really "works" for childrearing. One partner hunts while the other gathers and cares for the young. Human beings will always be looking for viable mates with better genetics though.

>>1805409
What was? Cloacae? >>1805251

>>1805422

GOD MEANT FOR WOMEN TO POOP LIKE SEAGULLS!

WHY ARE YOU QUESTIONING GOD????

>>1805438
I agree. All other animals just have one hole. Why do we get special treatment?

Yes, the vag has muscles and can contract. However, they do not close 100%, so, it's not very effective in stopping blood flow. Not sure about other women, but if I feel some blood comin' down the line, I do contract my vag muscles and that'll usually hold it till I get to the bathroom to put in a tampon.

Truth:

We can contract those muscles any time. We can contract them during sex to stimulate the bf.

The sphincter of the vagina runs the length of the vaginal canal. It is not merely at the opening to the vagina, that is why it is mostly ineffective at stopping blood flow.

The vaginal sphincter is relaxed and open normally, contrary to the anus.

During childbirth, when pushing, you do not push the baby out with the vaginal sphincter muscles. You push down with the diaphragm and abdominal muscles. If you squeezed the vaginal sphincter muscles, you'd hold the baby inside the uterus, since that is ABOVE the vagina.

>>1805517

You just gave me hope for humanity.

Thank you.

I really wonder why /sci/ hates itself so much.

>>1805595

Because trolls.

>>1804921
BECAUSE ALL WOMEN ARE FUCKING WHORES THAT JUST LIKE TO HAVE A VAGINA OPEN SO THEY CAN STICK MULTIPLE DICKS IN IT EVERY SECOND OF THE DAY!!!!

So that they remember where they started, duh.

It kind of has to be drained out, being able to hold it like that would be very dangerous.

Because it's an advantage to hold waste disposal functions in the bladder and anus until one can relieve themselves away from any food or water sources.

Women used to have to spend a week in a hut with other menstruating women.

I've always been confused by our ability to hold in piss and shit. And not just us, but lots of animals as well. I mean, how important can it be? Sure, some animals mark their territory, but I don't think most do. And what's going on with dogs when they wander off and take a dump? Why do they always look so guilty?

>>1805752

Why are you watching dogs taking shit?

Also, sanitation.

>>1805648
>>1805517
Yes, thank you.
Jesus.

>>1805447

don't most of the animals that only have one hole lay eggs?

dogs and cats have vaginas don't they? I dunno I never looked

>>1806341

>>dogs and cats have vaginas don't they?

Only the female ones.

>>1806403

so then the next question is

if dogs and cats have vaginas

why is /sci/ still so lonely?

>>1805752
>>1805752
>>1805752


because pissing and shitting where you eat and sleep is an evolutonary disadvantage for MOST species (some species developed excellent immune systems capable of battling most mutations of bacteria that live in their own bodies, which would be great for humans with mutant E. Coli)

I write my scripts in PHP and do mathematical stuff in Mathematica.
It gets shit done and I usually have problems easy enough to be handled by PHP, and the mathematical problems wouldn't be handle-able by programming them myself in a hundred lifetimes.

implying anyone on 4chan would know anything about the female anatomy

>>1806422

Good question. You'd think you would see more of this, considering that 100% of /sci/entists are closet furries/transhumanists/etc.

Pic related; it's the closest you're ever going to get to a real furry.

>>1806477
Woops, I have the slight feeling I've posted that in the wrong thread.

>>1806419
Yes but why the shame?

Why the shame?

Hmmm...
The question is irrelevant due to humans (and for that matter, most mammals) are the planets current dominant vertebrate.

But to go into a bit more detail, I will state this: the amount of blood menstruated would not have that much impact on the human body in the wild. I would be washed or wiped away before it would be any sort of problem.

I hope that makes up for the 130+ asinine post about whether people are actually women irl.

It does.

However wouldn't leaving a trail of blood attract predators?

And if that is so why can we still control our pee? Is there some evolutionary benefit to that?

>>1806937
