While commonly a mere euphemism for sexual intercourse (not necessarily unlawful), different jurisdictions have defined carnal knowledge (as well as sexual intercourse) as a specific sex act such as contact between a penis and vagina, some laws elaborating this to include even "slight penile penetration of female sex organs". The definition sometimes includes a set of sex acts that include sodomy, while some statutes specifically exclude such acts. Some laws do not define the term, and leave it to the courts to give it meaning, which also allows them to take into account changing community standards.
