Sexual assault refers to unwanted sexual contact that may involve force or coercion. Rape specifically refers to forced sexual intercourse, including penetration of the vagina, anus or mouth by a body part or object against someone's will. Sexual assault can include harassment, unwanted exposure or flashing, forcing poses for sexual pictures, or unwanted sexual touching. Most sexual assaults involve psychological coercion rather than physical force, often taking advantage of an intoxicated or incapacitated victim. Common reactions to sexual assault include shock, loss of control, fear, self-blame, and feeling vulnerable.
