Sexual abuse, also referred to as molestation, is forcing undesired sexual behavior by one person upon another. When that force is immediate, of short duration, or infrequent, it is called sexual assault. The offender is referred to as a sexual abuser or (often pejoratively) molester. The term also covers any behavior by any adult towards a child to stimulate either the adult or child sexually. When the victim is younger than the age of consent, it is referred to as child sexual abuse.
Sexual misconduct can occur where one person uses a position of authority to compel another person to engage in an otherwise unwanted sexual activity. For example, sexual harassment in the workplace might involve an employee being coerced into a sexual situation out of fear of being dismissed. Sexual harassment in education might involve a student submitting to the sexual advances of a person in authority in fear of being punished, for example by being given a failing grade.
