Sexual abuse of a child is generally defined as physical contact or other interaction between a child (under age 17, for example) and an adult when the child is being used for the sexual stimulation or pleasure of the perpetrator or another person. In addition to physical contact, sexual abuse of a child may include (1) the exposure of the genitals of an adult in the presence of a child, (2) the exposure of the genitals of a child, (3) using a child in making pornography, or (4) making a child view sexual acts or pornography.

And in some states multiple instances of sexual contact between an adult and a child may constitute the enhanced criminal offense of continual sexual abuse of a child—which is sometimes a first-degree felony offense.

In Maryland, sexual abuse of a minor is a serious criminal offense. Under Maryland law, sexual abuse of a child includes any act that involves sexual molestation or exploitation of a child, whether physical injuries are sustained or not. This can encompass a range of behaviors including, but not limited to, inappropriate touching or physical contact, exposing a child to adult genitals, involving a child in the production of pornography, or forcing a child to witness sexual acts or view pornography. Maryland's Family Law Article § 5-701 provides a detailed definition of sexual abuse in the context of child abuse and neglect. Additionally, Maryland Criminal Law Article § 3-602 prohibits sexual abuse of a minor and outlines the penalties for such offenses, which can be severe and include lengthy prison sentences. The state does not specifically define a separate offense of 'continual sexual abuse of a child' as some other states do, but repeated offenses can lead to increased charges and penalties under existing statutes. It is important to note that the age of consent in Maryland is 16, and there are specific statutes that address sexual offenses involving individuals under this age.
