For some people, simply using the bathroom around an hour before their session is enough to put their fears at rest. Some go slightly further, having a thorough wash around the anal entrance, or even using a douche to rinse out just inside their body.

The bag carries all of the liquid for your enema and will be suspended in the air at a greater height than your body.
