When I was 18, I had a time of great stress. It only lasted perhaps 3 days, but it triggered something in my colon: I didn't shit for two weeks in spite of laxatives. I was away from home, living in single quarters on an isolated mine. I felt no discomfort at all, but became very worried. What the hell was happening to all the hearty meals I was eating?
Well, eventually I began to feel 'things moving.' But when the 'thing' reached my unstretched anus, it was much too big to get out. It was also as hard as Satan's heart, and its presenting end wasn't tapered at all, but felt like the end of a food can! It had a smooth face that sat just inside my sphincter. What now? After heaving and straining for over half an hour (and getting VERY sore) I realised that this was a no-win situation.
I swiped a tea spoon from the canteen, retired to the toilets once more and after an age, the monster obstruction again presented itself. I had to chip at it with the spoon, and in a further half hour, succeeded in getting about an inch off its four inch diameter end. By then I had the beginnings of some really doozy piles and was very sore. there had to be some way to soften and/or lubricate things!
Next move was in the bathroom at my quarters. These were communal bathrooms: the tubs were out in the open. But I waited for the weekend when most of the guys had gone away, and then, late at night, I got into one of the tubs. with a little water in it, I scooted on my back until I could get my anus jasmmed up against the cold tap (faucet). Being young and lithe, it wasn't a problem to turn on the water and get an enema. I took as much as I dared. If anyone had approached, of course, it would have been easy to slip back into the water; though a little more difficult to hide the erection I always get from an enema! But no one came. I still had the tea spoon, and in spite of holding the water for quite a while, I still needed it. That night I got another two inches off the log! How long was it? I had no idea; and I also had an extremely painful arsehole.
In all, it took four sessions to remove what must have been a cylinder at least eight inches long and about four in diameter. I had puiles for years afterwards. But the episode left me in no doubt that the colon is a highly elastic affair, and can hold things far bigger than will fit through the anus!
Today I can take a six litre enema without trouble, and after a good clean out, seven and a half. Did I stretch? Maybe; but the evidence of all those years ago suggests that my capacity was always pretty big.
