Answer: A person can be charged with sexual assault of a child based on any sexual contact with a child under the age of 18. A child under the age of 18 cannot consent to any sexual contact. The severity of the charge is based on both the age of the child and the nature of the contact. Sexual contact is defined as any touching of the intimate body parts of a child or an adult. Sexual contact also requires that a person acted with the intent to become sexually aroused or gratified.
