I have heard the wildest stories in regards to this subject. Different utensils are used and the most dangerous acrobatics are performed on the toilet, but it is all so simple!
I sit down on the toilet seat, spread my legs and take the bag out of my underwear. I then open the bag and slide the faeces into the toilet and streak over it once more to empty it completely.
I pull both sides near the outlet tightly and clean it with folded toilet paper. With even thicker toilet paper, I carefully clean the inside of the outlet to remove the rest of the faeces.
I close the bag with the clip again, fold it and put it back into my underwear.
For the sharp smell, I find it useful to put two to three tablets of artificial sweetener into the stoma bag.
Unfortunately, I find that you cannot sit down on public toilets but even in a position with your legs apart or in the woods it is not a problem to change the supply after a little bit of practice.
