An anal douche is a simple device that is used to rinse the anus with warm water. Anal douches and anal douching prepares the anus before anal play or intercourse, helping to ensure cleanliness. An anal douche typically consists of a squeezable bulb connected to a nozzle. The bulb is filled with warm water before the nozzle is inserted into the rectum. This flushes out any faecal matter or residue making for a squeaky clean butt.
