There's an article in this month's maxim about how Hollywood folk frequently go get water shot up their asses until the butt can take no more water, and then it's all sucked back out along with feces upon feces upon feces. It's for cleansing purposes obviously, but in all seriousness you don't need to get this done. The body does it naturally. In fact going to get these enemas really isn't that good for you because dilating the rectum like that will end up causing loss of rectal strength down there after a while. Rectal strength, something we should all be concerned about. Stick a finger up there twice a day and squeeze to failure for 6-8 solid reps and everything should be ok.
