I don't remember anything but the big old red enema bag that smelled of rubber that was a combo hot water, douche and enema bag, and the screw-in hose at the end of the big red enema bag.
It has to have been a 2 qt. bag. And it seems even as a small child it was about 1/2 full. I remember lots of cramps with my enemas as a child. I don't think my mother went too far, but all I can remember is about 1 qt. enemas, but I'm sure far far far less when younger. My mother had had some nurse-type training. She never would have done too much, but she sure gave a good one.
I don't recall any bulb type enemas at all. Just being spread with my one knee almost to my chin lying on a towel on a large rubber sheet with my asshole totally exposed to the world. And the big old red enema bag, the long red hose, the well greased black nozzle and the click of the shiny chrome hose clamp, and the start of the water flow and waiting for the cramps to begin. Our family doctor prescribed enemas for everything. That was the only time I got enemas. He sure prescribed a lot of them. I did not like them at all from my mother and I was very afraid of enemas, but on my own, that became another story of good times!
At around 5 or 6 I started doing enemas myself. Had found an old enema hose and nozzle I use to stick in the cold water faucet in a remote bathroom. They were good ones, but I had to work fast because eventually the water got too cold from the well! There was no hot/cold mixer valve, just separate hot and cold water faucets. It was a very old bathroom. Then, later, I use to remove the shower head from the old hose type sprayer on the red hose in the bathtub that one use to just stick over the combo water valve in the old claw type bathtubs. And up went the hose up my ass after I had carefully adjusted the water temperature. That, I could do when people were home as all would assume I was just taking a bath.
Then, around 10, I use to fill the big old red enema bag all the way up whenever alone in the house, so I know I was probably getting about 2 qts. maybe.
When I discovered jerking off about 10, I found I could hold more, it was part of my fun. The mild cramps felt good as I slowly stroked my super hard dick, and then came in the washbowl directly in front of the toilet
Then, in high school, I was filling it up twice, so I know I was getting probably almost 4 qts., probably 3 around 14 or so, maybe more, in front of the toilet, with a washcloth pressed against my ultra super horny asshole so I did not spray all over the bathroom. When I did them on my own, I could control the entire scene. I do know I use to fill that enema bag really full, so full I had trouble getting the hose connection screwed back into the bag. I always did it in the bathtub it was so messy, then I took the bag over to the toilet to the well worn brass enema hook. And it was high up on the wall, probably about 4 feet above the toilet. When really young I use to stand on the toilet lid to reach the hook.
I had some really good times, especially on those times when I might be home alone all day. I use to look forward to those times trying to hide my super hard hardon in my pants in anticipation of some good enemas by myself. My hardons like that use to start several days ahead of time when I first heard my parents and sisters would be away most of one day on the coming weekend. Good times!
I do recall being quite surprised as I grew older when I heard people speak of small enemas. I had always thought in my youth any enema was a total fill up with as much as one could safely take. I had no idea there was such a thing as small enemas.
As a note, I'm not a fan of huge volumes, mine have always been safe. Never have I over done it myself or had that done to me. I've always had a fear of something bursting, so I am always super careful. What has surprised me is sometimes I'm really hungry for an enema and can take a lot, other times just a little and I'm full. I don't think it's how much poop I might have in me, it seems more related to how tense I have been, I think.
