As Arianna mentioned in her posting, I also enjoy and prefer to use a shower/tub as opposed to a plain shower.
In a tub, I can heat it with the water, hang the bag from the shower head and adjust the shower flow so as to continually fill the bag, lay back in a relaxed position, and let it flow slow and easy all the while being gently showered all over. I find that more preferable than taking while standing which puts tension on the abdominal muscles and makes one develop the urge to expel much more quickly.
Quite often in the past, I have done a three bag series before a tub/shower session to clean out large matter then headed for the tub and spent hours laying in there filling and releasing (nothing large is left inside,it is just washed down the drain by the shower with no problem) in total bliss and freedom. Orgasms you ask?.... oh yes, most definitely !
Sadly, since I moved into to where I live at present, there is no tub. So nowadays, when I have a strong desire for tub/shower enemas, I most often go to a local motel, and even more rarely,visit an open minded lady friend with a tub/shower who is willing to let me indulge myself and even on rarer occasions, indulge them in this gentle fine pleasure. 😃
