A word to the wise

The biggest Danger of Coffee Enemas is associated with the material itself: coffee. The majority of individuals injured while performing an enema using coffee simply used the liquid before it had time to properly cool. Using coffee that is too hot can cause great injury to both your anus and your intestinal tract, leaving you in great pain due to potentially dangerous burns. You should carefully test the temperature of coffee or any liquid you choose to use as an enema to ensure it is not hot enough to cause injury.

So no pouring hot coffee up your ass. Check. You might want to make a note of that, Lees.
