Now as far as your comment about buying enema equipment. Why are you embarrassed to buy some? Pooping is a human necessity. If you don't then you will blow up right? LOL. No one wants that to happen. You can trust me when I tell you, no one cares what you buy.
What I tell people who are embarrassed about buying a normal red bag that you can pick up at any pharmacy is to say something along the following lines, if, and only if you get a cashier that looks at you funny...
My wife has cramps and needs a hot water bottle for her belly. OR
My dog had puppies and I need a hot water bottle to help keep the puppies warm. OR
I hurt my knee and I am supposed to put ice packs on it over the next 24 hours and the nurse suggested buying one of these because they stay colder longer than regular ice packs and they will fit better around my knee. OR
You can just look her straight in the face and say something to the effect of, "I can't wait to get home and take a nice hot soapy enema, care to join me?"
Any of the above will work, you just have to figure out which one fits your life best. They can also be modified as well if needed. Good luck, and I hope you get over your fears and or embarrassments.
