Sexual assault is an act in which a person intentionally sexually touches another person without that person's consent, or coerces or physically forces a person to engage in a sexual act against their will. It is a form of sexual violence, which includes rape (forced vaginal, anal or oral penetration or drug facilitated sexual assault), groping, child sexual abuse or the torture of the person in a sexual manner. Child sexual abuse is a form of child abuse in which an adult or older adolescent abuses a child for sexual stimulation.Forms of child sexual abuse include asking or pressuring a child to engage in sexual activities (regardless of the outcome), indecent exposure of the genitals to a child, displaying pornography to a child, actual sexual contact against a child, physical contact with the child's genitals, viewing of the child's genitalia without physical contact, or using a child to produce child pornography,including live streaming sexual abuse. The effects of child sexual abuse include depression, post-traumatic stress disorder anxiety, propensity to re-victimization in adulthood, physical injury to the child, and increased risk for future interpersonal violence perpetration among males, among other problems. Sexual abuse by a family member is a form of incest. It is more common than other forms of sexual assault on a child and can result in more serious and long-term psychological trauma, especially in the case of parental incest. Approximately 15 to 25 percent of women and 5 to 15 percent of men were sexually abused when they were children. Most sexual abuse offenders are acquainted with their victims. Approximately 30 percent of the perpetrators are relatives of the child - most often brothers, fathers, mothers, sisters and uncles or cousins. Around 60 percent are other acquaintances such as friends of the family, babysitters, or neighbors. Strangers are the offenders in approximately 10 percent of child sexual abuse cases. Studies have shown that the psychological damage is particularly severe when sexual assault is committed by parents against children due to the incestuous nature of the assault.Incest between a child or adolescent and a related adult has been identified as the most widespread form of child sexual abuse with a huge capacity for damage to a child.
