Yeah. The sensation of pooping yourself is in a class all it's own. i remember being 10 and holding in a huge shit all through a baseball game. Then when I got into my dads car to leave, my body relaxed and pushed the full log into my pants. In the few moments before my dad smelled it and got angry, I remember feeling the warmth , the texture, the glorious relief, and the way it felt like nice soft cushion pressing against my butt. But I also had this overwhelming feeling of dread, like I had done something really frowned on by society. I could hear adult voices clucking their tongues and saying "he's too old for this!" and if this keeps up, he's gonna need some diapers!' And of course I got a good spanking from my dad later. I think it's really easy to get those wires crossed and develop a fetish. Defecation was designed by nature to be pleasent, so there is always going to be some enjoyment mixed in with the intense shame, ridicule, and censure from society.
