Child Sexual Abuse (CSA) is defined as the sexual touching or penetration of children. The definition generally includes attempts as well as completed assaults. There are other forms of illegal or unwanted sexual experiences such as exposure, peeping, or sexual harassment in the form of talking in a sexually inappropriate or intimidating way.
Problems of Estimating the Victimization of Child Sexual Abuse from University of New Hampshire
All forms of sexual contact by an adult with a child are illegal regardless of the circumstances, the use of force or threats, or the child's behavior. The law is based on the premise that children are unable to consent to sex with adults.
The law also applies to teenagers who use force to have sex or have sex with children who are significantly younger. The same laws apply to teenage and adult offenders, although the penalties are different. The laws that are specific to children do not require proving that force was used or that there was a lack of consent. The child-specific laws make some distinctions based on age differences between the victim and offender.
Sexual contact by a child under the age of twelve with a younger child can only be prosecuted under very specific circumstances. When the offending child is between the ages of eight and eleven it is possible to prosecute if certain legal requirements are met, but this is rare. Children under eight years of age cannot be prosecuted regardless of the behavior.
