The anus may have evolved from a hole originally used to release sperm
But whose sperm are we talking about here?
When two people kiss, they form a long tube from one anus to another.
While two people, sitting on toilets interconnected by sewer pipes, form a long tube from one mouth to another.
I’m not sure you’re supposed to form an air-tight seal around the toilet bowl, but if your farts are that bad then thank you for your consideration
if you have more than one toilet you can start a LAN party
))<>((
not the way i kiss >:3
From Robin Williams describing the reproductive system …
“What was god thinking when he designed humans? … let’s put the waste disposal system next to the entertainment system!”
Don’t even get me started on breathing and eating through the same set of tubes
I’m convinced this is how I’ll die, I regularly get it down the wrong hatch and some day that piece of chicken or whatever will just be a bit too big to get it out/in again… Now that I think about it, it hasn’t happened in a while, maybe just so I let my guard down…
i’m just glad we have noses so we can breathe while chewing
I really commend the creativity and dedication to detail the graphic artist took on this spectacularly breathtaking image.
Meanwhile, there have been very rare instances of women getting pregnant from getting fucked in the ass.
Hey, some people have subtle deformities allowing fluids and such to travel where they usually don’t…
Transanal-transvaginal fistulae. That was a bad day to have eyes, or the ability to read. Ah well.
No more poophole-loophole :(
And that, is why it feels good to fart.
The poor man’s orgasm
why the random, comma?
A comma can be used to improve readability, but it can also indicate a pause while talking. I feel a pause after “and that” is as common as no pause. That said, I cannot know if that was the poster’s intent; it’s only my interpretation of the usage.
It wasn’t random, it was intentional 🙃
I honestly would’ve thought that an orifice to release waste products came first, but I’m not an evo-devo-nist.
Yeah, the first thing the embryo of vertebrates folds into is a torus whose hole will become the digestive system. Reproductive organs come way later.
So very early in our development we’re just an asshole. Some people apparently never make it past this stage.
Not to mention that animals with reproductive systems but that reproduced asexually evolved long before sperm.
e.g. earthworms
Yeah it feels like a weird way to say that humans still have vestigial signs of a cloaca. It’s understood that evolutionary ancestors did, so humans’ ancestors would need to have separated the functions during their evolution… I guess the news is that there is still genetic evidence even today.
Alternatively, creationists can take this as a sign a creator considers butt stuff to be natural sex also 👍
i think the creationist response is that humans were always exactly like this and any evidence pointing to the contrary is put there by god to test us
… but also worth a try - it’s not like they actually think about things
WHO ARE ALL THE PEOPLE ASKING THIS QUESTION???
What question might that be?
Where boobies come from?
Where booties come from?
🤔
Why, God?
What is it with vertebrates and combining reproductive organs with the out-end of the digestive system? Don’t they get it’s gross?
For many, it still does

I used to date a lady that would, during foreplay, comment that I really needed to ejaculate bad. Not the exact wording used, but it was still a little weird. Not weird enough to break my stride, because it was true enough, and with her working the pieces parts that would lead up such an event, it could have been extremely weird, and I would have been okay with it.
This goes on for months before she finally said, “I don’t know how it fills up so fast, we just did it an hour ago.”, during a rather busy weekend that included a great deal of ejaculation. I asked her what was filling up so fast. She said “your balls, they just get so big when they’re full.”
This lovely, wonderful lady had made it into her early thirties under the impression that all of the semen was produced and stored in the testicles, filling them up continuously. She was also under the impression that testicles would rupture if not drained regularly.
She attributed this to something she had overhead someone say in jr high, and had apparently never figured out otherwise.
It kinda makes sense. Why would the sack be so big and stretchy if it didn’t need to hold balls that would expand. And why would guys have different sized ones if some of them weren’t draining them more often than others.
The ensuing conversation was a difficult one. Partially because it stopped the previous activity, partially because she had a lot of questions, and partially because it wasn’t clear if the frequency with which she wanted to prevent my testicles from exploding would decrease.
Luckily, the conversation went very well, and they did eventually explode in the usual way, which was much more entertaining for her than before, she said. It also led to a lot of fun as she developed an almost fetish about feeling the event happen whenever activity would make that possible.
