I joined this site about a week ago. I enjoy enemas for a variety of reasons, including health, punishment/BDSM, and sexual. I thought that I might be unique in my enema practices, but it seems that I'm not. First of all, you should know that I don't like looking at feces, in any form, not even my own, not even my cat's. It just grosses me out. (I have a photographic memory, so such experiences stay with me for quite a while.) For this reason alone, I prefer to take my enemas outside, where I evacuate in a shallow hole that I dig. I live in a suburban neighborhood and, while my backyard is fairly private, I can be seen by my neighbors, so I take my enemas at night (after midnight). It is here that the BDSM part enters, where I am forced by a fantasy Dominatrix to take a series of enemas, prior to any kind of anal play.
The first couple are usually plain water, which are then followed by two Castile soap/salt enemas. Next is a two-liter coffee enema, which I am forced to hold for at least twenty minutes while in a kneeling position. For every accidental leak, I am forced to extend my retention for another five minutes. Whenever possible, I time this during a rainy night. In my mind, the act of cleansing both internally and externally is both holistically healthy and sensually erotic. I can feel every drop of rain as it strikes my skin, and then runs down my naked body. There are few things as purifying as rain (poetically-speaking, at least). Then, to be forced to expel the enema outside, adds a humiliation facet to the whole experience. Sometimes, I'll chain myself to an immoveable stake in the middle of the yard, making it impossible to even seek shelter under a tree. No, I don't do this if there is a forecast for lightning/thunder!
I live in the northeastern parts of the United States, so such experiences are limited to summer and fall (spring nights are still too cold). I'm not bothered by cold rain, but it needs to at least be 60 degrees F (I'm a masochist, not crazy or stupid).
Thanks for letting me share!
