An ass diet is the procedure of introducing liquids into the rectum and colon via the anus. The increasing volume of the liquid causes rapid expansion of the lower
intestinal tract, often resulting in very
uncomfortable bloating, cramping, powerful peristalsis, a feeling of extreme urgency and complete evacuation of the lower
intestinal tract.
This procedure can result in weight loss.
An ass diet may also be used prior to anal sex or anilingus in order to enhance the sensation of
intercourse, or to remove feces prior to sex, possibly reducing bacterial transmission and risk of infection, or just to reduce the
possibility of fecal material or detritus from
sexual activity adhering to the genitals or sex toys used during the subsequent activity. An ass diet used before anal sex should not be used consistently and contents should be removed afterwards. Continual usage of an ass diet may be harmful for the anal cavity.
