Felching is a sexual practice in which a person sucks semen out of his or her partner's vagina or anus. The semen is usually that of the person doing the sucking, though this is not always the case.

The term can also refer to sucking enema fluid from a person's vagina or anus, though this definition is much less common. Water, urine, beer, or wine are often used in this kind of enema, though introducing alcohol into the anal cavity carries the high risk of death through alcohol poisoning.

The term is also used in reference to several other sex acts, specifically:

• the act of inserting animals (more specifically, rodents such as hamsters, gerbils, mice, etc.) into the anus or vagina, which is a form of zoophilia, see gerbilling; or
• the act of defecating on one's partner's torso, which is a form of coprophilia.

Felcher is used as derogatory term; goat felcher is popular on many internet forums. Felcher has also been used as slang in the United States Air Force to describe airmen who masturbate excessively.
