I have a tendency to relate most enemas with their sensation value. Standing offers different sensations than, say, laying down in the tub, or taking an enema on your stomach in the bed. I will go with the mood I'm in and the sensation I'm seeking at the moment. I am, I believe, a true Klismo, and don't believe there is a bad position from which to take an enema. Standing offers a very heavy downward sensation when trying to take more than 3 quarts. I enjoy it very much, however, I have a hard time retaining it more than about 10 minutes. That will not deter me from trying over and over again.
