Felching is a human sexual behavior involving the licking or sucking of another person's anus. This practice involves a high health risk. In particular, it refers to the act of sucking semen out of the anus of one's partner. The semen has been ejaculated into the rectum via anal sex. The act of sucking the semen and then passing it, through mouth-to-mouth or open-mouth kissing, is often referred to as "snowballing"; although the latter is typically associated with semen ejaculated into a mouth from fellatio. Felching may also uncommonly refer to the anal insertion of a small animal for the purpose of sexual stimulation.[1] The animal allegedly most used is a gerbil, and hence the act is better known as gerbiling. There is debate as to whether gerbling is a concept sustained by urban legend or actually practiced.
