==Butt eating and ass eating== 
 Both terms for the buttocks are in common usage so i added it.  
 ==lingus link== 
 lingus should not link to cunnilingus, since in latin it means tongue so it should link to tongue, perhaps the text should however point out the origen of the term anilingus was by analogly (kidding) with cunnilingus  

 == nose == 

 people also use the tip of their nose to stimulate the anus and the article should mention people insert their tongues inside the butthole.
