Sexual assault is generally forced sexual intercourse, sodomy, or other sexual penetration of another person—against the person’s will and without the person’s consent. And although precise definitions and punishments vary from state to state, the criminal offense of aggravated sexual assault of a child includes the aggravating circumstance of the victim being a child under a certain age, as defined by the statute—which increases the severity of the crime.

In California, sexual assault is defined under various sections of the California Penal Code, including rape, sodomy, and sexual penetration, all of which are illegal when performed against someone's will and without their consent. The definition of consent is specific and does not include instances where the victim is incapable of giving consent due to incapacitation or mental disability. Aggravated sexual assault of a child is a more severe crime and involves a victim who is under the age of 18. This offense is addressed under California Penal Code Section 269, which specifically deals with aggravated sexual assault of a child and includes harsher penalties when the victim is under a certain age, typically under 14 years old. The law recognizes the vulnerability of children and imposes strict penalties, including life imprisonment for certain offenses involving minors. It's important to note that the age of consent in California is 18, and any sexual activity with a person below this age is considered statutory rape, which is a form of sexual assault.
