I have been taking two successive enemas every morning for several decades.
I usually take these successive enemas standing up! So the bottle is about a meter above my intestines.
I find standing very practical when you're alone!
Sometimes I get on all fours to speed up the filling, then I have to get up by clenching my buttocks!
The 2-liter bottle is attached to the top of the shower.
It is a translucent bottle that allows you to see the water level going down. I added a flow indicator, a wheel that turns more or less quickly depending on the flow.
I use a Titanic nozzle from Klystra, which, due to its shape, provides a good seal when standing up, because when the pressure rises, if the cannula tries to come out under the pressure, the diameter at the sphincter increases, facilitating the watertight retention.
The water temperature, around 42 degrees, allows easy introduction of water while avoiding cramps.
The 2 liters flow quickly, in about minutes, and at the end of the flow you hear a characteristic little gurgling sound that all enema patients know well!
during flow, sometimes the pressure rises too much, so with my feet I press the pipe hard on the ground and this regulates the flow, but in the end I really like this internal pressure which rises!
When things go too easily, I stop the flow of water before the end of the bock and I add hot water to the top!, I then reach the volume of three liters and more.
In general I do not hold the water for long, I sit on the edge of the toilet bowl, I remove the nozzle, and the flow of expulsion under pressure spurts out. Afterwards it is more peaceful, the internal liquid finds its way back at intervals, and during this time, I write on Zity or I publish my erotic photos of enema, which I like to share with connoisseurs.
I would have liked to meet an enema expert like there are on Zity, who forces me to take more and keep it longer.
