OK, so I took care of my dad's bodily needs for awhile, before his death, and it was sometimes overpowering, with smells that lingered in my nose for days. I should have used Vick's, or something, but it was a learning experience in how to take care of someone's poopy problems. Usually cleanup meant a quick shower, but that wasn't always possible.
As for me, I've done it, but found the smell & cleanup more of a turn off than a turn on. I do like the feel of having "something" in your pants (bananas, oatmeal, squash, etc), and I get that experience ever so occasionally. My suggestion to anyone hoping to enjoy the real thing is some Immodium, diaper cream, and holding it longer than usual, resulting in a firmer poo, and less stickiness. I think.if you hold it longer, using Immodium, they're more log-like (your colon removing more moisture), and probably just a wee bit more manageable.
Curiously, even though I'm not a fan of poo, I'd like to be forced into using a tunnel plug, for the ultimate humiliating experience of having no control, and a poopy diaper result, but skip the Immodium & attempts at retention, in that case. That should be all about loss of control, for humiliation's sake, but even a tunnel plug could be used with some banana/mashed potatoes/squash stuffing up the poop chute, for extended play.
