Although I also wouldn't think of myself as someone into scat, as I wouldn't play with poop, I have to say that maybe things are a little more complicated in my opinion.
I mean, when someone has fun with enemas, part of that fun is in giving someone else (when you have a partner, of course) the control over a very intimate and private act. Whether you are into giving or receiving, I think that it's part of the thrill.
And also when you experience some cramping (at least until they aren't too bad) and you're enjoying them with another person, well those cramps are definitely related to the act of releasing.
Personally, I am not into touching the poop in any way, yet I have to say that I like being close to my partner when he releases the enema and poops, I like having him sitting on the toilet with his head on my belly, holding and stroking it, even encouraging him to get rid of everything. I find that tender and although some part of myself doesn't like to link that to scat in any way, I have to admit that it's maybe related someway. And maybe it's not by accident that someone here is even turned on by constipation (I am among them); it's not only a good excuse 😉 for taking or giving suppositories and enemas, but it's also a psychological plus in many roleplays.
This is of course only my point of view, and I like so much the fact that we were given here the chance to discuss a topic like this, whatever our opinion, and especially when we are able to express our points without being judgeful with the others. This is such a great site!
