How many enemas do you take in a series/session?

I usually receive a soapy enema and a rinse, but if the rinse comes out dirty I still receive a soapy one and a rinse

Usually just one enema two quarts plain water. Frequency is 2-3 per week. Denise

Just one enema most of the time with plain tap water at 103 degrees F (40 C). Occasionally, I will do a second enema. Sometimes I will add a little Johnson and Johnson Baby Shampoo at the recommendation of @Denise and I find that to be mild and satisfying and no need to even rinse according to @Iris1858 .

Every so often I will use a little Dr. Bronner's Peppermint Soap if I want some zest and little tingle in my bum.

It's usually 4-5 using various solutions and enema tubes/nozzles. By the time I'm done I'm totally cleaned out, which is the objective. Got be ready for my anal play that or the following day. Quantities start at 2 quarts and increase about a half quart until I'm up to 3.5 quarts, and on rare occasions 4 quarts.
