For some of us products of the 50's and 60's, we likely had bowel managers in one way or another. My mom and grandma were certainly the managers of our bowel habits as youngsters. The family pediatrician was available, as was his nurse, to lend support, advice, and encouragement to their efforts.
As one whose elimination was managed on a regular basis, I resisisted, resented, and eventually capitulated. If an enema was forthcoming, it eventually was easier to go with the flow and avoid the pain of physical intervention. I even began self-administering to avoid lying about having had a BM when the inquisition came.
It's funny how a half century, or multiple decades, have altered some of those early perspectives. I find myself managing my own bowels on a pretty regular basis. If I'm going to be on the road, an enema prior to travel is rather convenient. If I'm going to be in a position that toileting is challenging, an enema is quite efficient. If I'm fortuitous and can anticipate some playful manipulation of my prostate, an enema certainly enhances foreplay and prepares the magical venue.
The biggest challenge is finding the right individual, with whom I can relinquish the various aspects to, and still maintain an otherwise typical, sometimes mundane, existence.
