Rape of a spouse.

(1) Existing law defines rape as an act of sexual intercourse accomplished with a person not the spouse of the perpetrator under certain circumstances, including where the victim is incapable of giving legal consent because of a mental disorder or developmental or physical disability, where the victim is not aware of the essential characteristics of the act due to the perpetrator's fraudulent representation that the act serves a professional purpose, and where the victim submits to the act under the belief that the perpetrator is someone known to the victim other than the perpetrator, and the perpetrator intentionally and fraudulently induces that belief.
