Ok, let me see if I can get this right... ???
First, there may be the embarrassment, and then the ensuing excitement of being told that one is going to receive an enema. For many, the first statement brings about a variety of emotions and a blurring of thoughts, coupled with the anxiety of knowing that they are going to surrender to a most intimate experience. And, yes, the enema entails at some point in time, the presentation of a denuded nether region. How the buttocks get to that state can be a tantalizing and sensual aspect of the procedure.
And, if that isn't scintillating enough on its own, there is the moment at which the administrator would spread the buttocks, gaze upon the anal orifice, and then proceed to apply a lubricant to make access by the enema nozzle a simple journey. And, when the lubricant is applied to that sacred of all openings, and the relaxation reflex is noted, coupled with the patient being asked to bear down, the properly dressed finger will invade the anus to spread lubrication onto the interior surfaces of the sphincters to allow easy passage of the nozzle though the anus and into the rectum.
Once all is done, the enema solution can be started... And, for lots of people, this experience at any stage, can take on sensual proportions that for many may even be equal, or greater, than the sexual act. And enema can bring about burgeoning tumescence, be rich in emotional & psychological overtones, and a most intimate sharing between two (or more) people. At a minimum, many will find an enema to be a relaxing sojourn, in addition to enjoying its cleansing qualities. Thereafter, there can be a state of total relaxation, and even rejuvenation. And, yes, there can be a state of total sexual excitation too.
Well, that's kind of it from this part of Texas on the subject of "Why do we like enemas"?
No ~ go find a friend and enjoy yourself!!!
