Seems to me too many of you are just plain ignorant. Of course shit comes out the hole, but so does urine (and a couple of other things) come from a fanny (and your rod for that matter - and how hygienic is that? Or does that make us all golden shower freaks?). The secret (?) is douching. There are even specialised devices designed to properly flush those holes and get them cleaner (and a lot more hygienic and less smelly) than most of your mouths. Very few people would even consider rimming (or being rimmed) if there was even a hint of it not being completely hygienic, let alone nibble on peanunts and raisons! (unless of course you were into rather alternative sex such as scat etc.). I mean, most people would just not find it sexy and probably be offended/embarressed (depending on whether you were giving or receiving). So all the stuff mentioned which one might find offensive, should not even be under discussion.
