Sexual abuse (also referred to as molestation) is defined as the forcing of undesired sexual acts by one person to another. Child sexual abuse refers to situations when the person this is done to is a child.

Different types of sexual abuse involve:

• Non-consensual, forced physical sexual behavior such as rape or sexual assault
• Psychological forms of abuse, such as verbal sexual behavior or stalking.
• The use of a position of trust for sexual purposes.
• Incest, when it is coerced by force or emotional manipulation; the euphemism "bad touch" is sometimes used to describe such abuse.
