This came up when I was searching for prostate (well, actually it was http://www.zity.biz/index.php?mx=forum;ox=display;msg=348172 , but this post has more comments).
While the whole "messing the diaper" thing leaves me kind of 'meh', the description of the sensations was very interesting, and the thought of being able to lay back and "relax" because you don't have to worry about actual fecal material if/when you let go also appealed, because then you can focus on the sensations without worrying about "what happens if I let go" (other than a slightly sticky cleanup).
So I tried it (I'm having a bit of a butt-wild week and then some because my work schedule leaves more free time, and I've been wanting to boost my anal play). I didn't have diapers, wasn't too interested in buying a bunch, so I used a couple of old bath towels lined with paper towels for easier clean-up. I considered just using willpower, but eventually came up with the towel thing just in case.
Cleaned out, squirted in some glycerin (I used bulk glycerin, so more than the "recipe" called for), slipped in 3 glycerin lubed bananas, then a rolled-up Always Maxi 8-hour pad, and waited.
Didn't have to wait long. Strong urges started within about 20 seconds. I clamped down tight to give time for the pad to expand and do its plug work. I had pretty much consistent urges and rectal contractions, with occasional 20-second breaks. At 7.5 minutes my sphincter was tiring, so I checked where it said
as the kotex begins to absorb the moisture from the bananas, it slowly expands and forms a snug and incredibly effective plug. ...
if [the sub] relax their sphincter (and eventually they have to); they find that they are absolutely 100% sure they are about to fill their pants, but at the very last second...they don't.
and gratefully relaxed. Ka-boom, all the bananas shot out into the towel. I tried loading up again (probably recovered about 2.5 of the bananas), pad back in along with squirt of water to help it expand, clench-clench-clench for a minute or two, relax and... Ka-Boom.
The pad was wet, but it didn't expand much and was squishy enough to pop out easily. I imagine that my internal sphincter is compromised or nonfunctional from persistent constipation from childhood on, which doesn't help either.
I'd be willing and interested to try it again if it can be set up so that the bananas are held for the 30-60 minute time, because those sensations rather than the mushy stuff against my butt is what I'd be after (the prostate stimulation leading to uncontrolled urination also sounded interesting to try once).
Checking the house we have some Always 10-hour night-time pads (black package), the pink super-capacity things that my wife got after our child was born, and some disposable diapers that might be able to be cut.
Anyone have "retention problems" with this? Any advice on fixing it?
