What Goes in an Enema? Mixtures, Saline and Goo

Almost everything that goes into an enema starts from the same base: normal saline. The rest comes down to temperature, the right thickener if you want goo, and knowing what is safe to add. This is the short version, with links to the detail.

General reference only, not individualized medical advice, and use-at-your-own-risk. The full explanations and sources are in the Enema FAQs.

Why saline, not plain water?

Plain tapwater works, but at volume it leaches electrolytes and can cause water intoxication, which at best leaves you tired and at worst is dangerous. Normal saline avoids that: nine grams of preservative-free salt per litre, which you can buy pre-mixed or mix yourself. Full detail →

What is in the goo?

Every mixture starts from that saline base. For goo, a thickening agent is added, either corn starch or tapioca starch. Past that, the recipe is a trade secret. More on mixtures →

A note on food coloring

Not all food colorings behave the same way, and some can irritate the gut, so introduce a new one cautiously. More on mixtures →

Temperature and retention

Two things make a mixture easier to hold: temperature and arousal. Keep the water near body temperature throughout (a sous-vide machine makes this easy), and use syringes or a Higginson syringe when retention is the goal, since the body adjusts to the pressure with each injection. The more relaxed and aroused your submissive is, the easier it is to hold. Full detail →

High-volume retention in action

Is it safe to add food, like boba?

Tapioca (boba) pearls are among the safer things to add: cooked without sugar and coated in lubricant, they are soft, solid and non-sticky, and the body is well adapted to expelling solids of that consistency. Very few foods pose real risk. As with any insertion, use plenty of lubricant and listen to your body. Full detail →

The bottom line

Start with saline, keep it near body temperature, thicken with starch if you want goo, and add anything else carefully and well-lubricated. Read the full FAQ for the detail, browse previews by model, or see the latest clips.
