An anal douche requires infusing water or saline into the rectum to remove the faeces in it, making it easy to poop. We recommend that you do so before anal sex to prevent any poop from emerging. Anal douching is typically not dangerous as long as the rectum is not irritated. Only do it once every several months while properly following the instructions. If your bum gets irritated when you do enemas, that is an indication that you should stop.
