I've read several postings on the Zity enema boards about colonics, and have come away with the impression that most of those posters were enthusiastic about colonics. I am not sure where the negative impression comes from.
Anyway, my first colonic was in Atlanta, by an man who looked to be in his 50s. He took me to the front room of his home-based business, and had me fill out a current state of health questionnaire, and a couple of other documents (probably a release form as well). He asked me if I had any knowledge of colonics. When I said I had a vague idea, he then told me about the process (his machine, tubing and speculum, how much water would be used, and the amount of time the procedure took). He might have explained the health 'benefits' of a colonic, but he didn't push any sales pitch. I told him I didn't feel well, and that I had very irregular bowel movements over a period of days. He then took me into a big room, which had a table in the middle of it, along with the machine to the side of it. The room had large windows, with the shades closed, but it was still very well lit.
He showed be to the bathroom adjacent to the colonic room, told me to strip completely, and put on the gown he handed me. I do so, and reenter the colonic room. I see he installed the tubing and speculum, and placed them on the table. He has me hop on the table, and lay down. He then instructs me to lay on my left side, with my knees drawn up towards my chest. He lubes the speculum, then my asshole, and inserts it. He then tells me to roll on my back, and bend my legs to a 90 degree angle, to put me in a more comfortable position to receive the onslaught of water.
Once my feet were firmly planted on the table top, he begins the flow of water. As the water is flowing, he moves the gown out of the way, so he can massage my distending belly. After I tell him I've full, he turns the valve on the hose, and I feel the water being released. He then begins to massage the right side of my belly, telling me he's working near the valve connecting the small and large intestine. As he does so, he pushes the gown up to my upper chest. At that point, I should have taken the gown off, as it was useless. I might as well been completely naked (and probably more comfortable). He then turned the valve, so the flow started again. The opening and closing of the valve was repeated several times, until he saw nothing else coming out of my colon.
When the water from the last fill cycle drained from me, he had me roll over to my left side, and pulled the speculum from my backside. . He then instructed me to go to the toilet, and release any remaining water and rub my belly in a clockwise, and counterclockwise motion. After that, I changed into my street clothes, and met him in the front room of the house. Since he was only open on weekdays, it would be tough to schedule another session (do to me being on military training status, I only had weekends off). Again, he doesn't give me a sales pitch, except for saying I was welcome back for another session. Unfortunately, that never happened.
