A. Incest is sexual relations or sexual contact of any kind with a relative so close that marriage is illegal. On this site, we talk about incest in the context of child sexual abuse. In fact, the definition of incest in the On-line Medical Dictionary states that "incest involving a child is a form of child abuse". Incest can include inappropriate touching, display of genitalia, and sexual intercourse. No matter what state or country you live in, there are strong laws and swift reactions to protect victims of child sexual abuse and incest.
Incest may also occur when there is an imbalance of power between the people involved, as in a relationship between a teacher and a student. Stepparents and stepchildren relationships seem to blur the line, but generally any sexual contact between legally related persons is considered incest.
