My wife likes to dominate me sexually and I find it stimulating as well although it does have unpleasant aspects. She has given me suppositories but especially likes to make me drink a foul-tasting laxative, either by itself or more frequently as a preliminary to an enema to fully flush me out. She is especially fond of administering a disposable phosphate enema to me orally as I kneel in front of her. The ingredients and dosage are identical to Phospho-Soda and even cheaper. It works as fast as a bottle of Citrate of Magnesia, and tastes far worse.
