He clenched. He crossed his legs under the table. He performed the ancient art of the tactical kegel . For an hour, it worked. But the colon is not a piece of code you can simply comment out. It is a muscular tube with a biological mandate.
Leo stood up to get more water. That was his mistake. Gravity is the partner of the rectum. As he walked, the stool descended. He felt a sudden, undeniable presence . Not an urge. A reality. The internal anal sphincter—an involuntary muscle you cannot clench—gave a tiny, reflexive relaxation. It’s the body’s way of sampling the merchandise. Is this a gas? Or a solid? It lasted only a second, but Leo felt it.
That stool collects in the rectum, the final holding chamber. Your rectum has stretch receptors. When it’s about 25% full, they send a signal to your brain: Hey. Might be time to find a bush. That’s the first urge. You can ignore it. The rectum relaxes, the stool slips back up into the colon, and the sensation fades for a while. pooping hidden

By 2 PM, the pressure had transformed. It was no longer a simple urge. It was a rhythmic, cramping wave—the colon’s mass movement. The body, in its infinite wisdom, knows that after a meal (and Leo had just choked down a sad desk salad), the colon gets a surge of activity. It’s called the gastrocolic reflex . It’s why morning coffee works so well.
The medical term is rectal hyposensitivity . The nerves get tired of screaming into the void. They stop screaming. Over months or years, you lose the urge entirely. You don’t feel the need to go until the stool is so large and hard that it’s practically a geological formation. That’s not a poop anymore. That’s a bowel obstruction waiting to happen. It can lead to impaction, where manual removal is the only option. Or a perforation. Or a stoma bag. For an hour, it worked
