A Victorian woman who killed her husband after he constantly demanded kinky sex has been jailed for 11 years.

Eileen Mary Creamer, 53, was the first Victorian woman to be found guilty of defensive homicide.

The Supreme Court heard Creamer severely beat David Creamer with a club-like instrument, possibly a South African tribal stick, before stabbing him in the abdomen at their Moe home in February, 2008.

During her trial Creamer claimed her husband made constant demands for her to have sex with other men in front of him and had been violent and abusive to her in the lead-up to his death.

The jury was satisfied domestic violence occurred and found Creamer not guilty of murder, but guilty of defensive homicide.

Justice Paul Coghlan said Creamer and her husband had a dysfunctional relationship.

He said Mr Creamer died after a "very substantial" beating that demonstrated Creamer was "out of control".

Justice Coghlan ordered South African-born Creamer, who is also a former New Zealand resident, serve at least seven years in prison before being eligible for parole.

She has already served nearly two years in custody.
