I often take a series of plain tap water enemas while lying in the bathtub or bathroom floor. Obviously, having my bowels filled with water for a while means that some of it will be absorbed, and then it's not just my colon, but my bladder also that starts getting full. 😉 But since I'm not worried about making a mess (I even expel in the tub after I start getting clear returns), I just keep relieving my bladder while I'm taking my enema. It makes it easier to focus on retaining the enema. Do others do this too, or do you prefer to hold it in until you're done with the enema and are ready to expel it?
