Here are all the facts, experiences, techniques and media/links we have on:
Anus
also known as Asshole, Sphincter
MEDICAL DEFINITION: The terminal end of the digestive system. It is the last inch or so of the
rectum, composed of two circular sphincter muscles. In its normal state, the
anus is closed tightly. During elimination of feces, the sphincter muscles
relax, and the anus opens to allow passage of stool.
SEXUAL DEFINITION: The entry for anal sex.
