I was five or less, and what I remember are:
Face down on a green rug in the bathroom.
I had watched my mother mix a strong Ivory Soap solution... I remember the smell.
A rubber rectal tube and funnel, and her constantly asking if I could take more.
I was encouraged to take as much as I could.
I have no idea how long I had to hold it.
The first squirts were soapy water. I thought I was done, but mum knew better.
I think I got up and walked around, and then it hit me, so back on the toilet with good results. That felt good.
I thought I was done, but while I don't remember much about them there were at least a second or third enema.
The most vivid visualisation, looking up at my mother as she poured the water in the funnel, and later looking in the toilet at the clear but soapy water before the dam broke!
What I do realise, this was not my first enema, because I think I remember knowing what was coming when I was called to the bathroom. Later I learned I received enemas from infancy.
My mother would talk about how good I was when she gave me an enema and that I would "go" right away for her. I wonder if she realised I was good because I loved what was happening... I think she did.
I also remember I looked forward to every enema I got after that one, to this day!
And one other fond memory, the praise I got when I graduated from the funnel and rectal tube to the Davol Petal bag. I quickly learned I could look at the bag and see how much I had taken and how I wanted to be a good boy and take the whole bag. From memory of how the bag looked I'd guess I was a quart and 1/2. Over time mum would fill it to the brim.
One of my best memories along that line was year later when I was having an enema at Mildred P. Burgess' colonic clinic. I had easily taken the entire two quarts, and she suggested she add more water to the bag... I think I made it to the gallon club a time or two.
