"Forced prostitution" generally refers to conditions of control over a person who is coerced by another to engage in sexual activity.
The issue of consent in prostitution is hotly debated.
Child sex tourism results in both mental and physical consequences for the exploited children, that may include "disease (including HIV/AIDS), drug addiction, pregnancy, malnutrition, social ostracism, and possibly death", according to the State Department of the United States.
Children are commonly purchased and sold for sexual purposes without the parents knowing.
Concubinage was a traditional form of sexual slavery in many cultures, in which women spent their lives in sexual servitude.
In some cultures, concubines and their children had distinct rights and legitimate social positions.
In contrast to the crime of rape, which is a completed offence, sexual slavery constitutes a continuing offence. Forms of sexual slavery can, for example, be practices such as the detention of women in "rape camps" or "comfort stations", forced temporary "marriages" to soldiers and other practices involving the treatment of women as chattel, and as such, violations of the peremptory norm prohibiting slavery.
In some parts of the world, child prostitution is tolerated or ignored by the authorities.
Reflecting an attitude which prevails in many developing countries, a judge from Honduras said, on condition of anonymity: "If the victim [the child prostitute] is older than 12, if he or she refuses to file a complaint and if the parents clearly profit from their child's commerce, we tend to look the other way".
The text of the Rome Statute does not explicitly define sexual enslavement, but does define enslavement as "the exercise of any or all of the powers attaching to the right of ownership over a person and includes the exercise of such power in the course of trafficking in persons, in particular women and children" (Article 7.2.c).
Sexual slavery is a particular form of enslavement which includes limitations on one's autonomy, freedom of movement and power to decide matters relating to one's sexual activity.
