Until 2012, the Federal Bureau of Investigation (FBI) considered rape a crime solely committed by men against women.
In 2012, they changed their definition from "The carnal knowledge of a female forcibly and against her will" to "The penetration, no matter how slight, of the vagina or anus with any body part or object, or oral penetration by a sex organ of another person, without the consent of the victim." The previous definition, which had remained unchanged since 1927, was considered outdated and narrow.
In addition, verbalized 'no' to sex may be interpreted as 'keep trying', or even 'yes' by offenders.
Some may believe that when injuries are not visible, the woman must have consented.
Incidences of rape are classified into a number of categories, and they may describe the relationship of the perpetrator to the victim and the context of the sexual assault.
These include date rape, gang rape, marital rape, incestual rape, child sexual abuse, prison rape, acquaintance rape, war rape and statutory rape.
Rape is a type of sexual assault usually involving sexual intercourse or other forms of sexual penetration carried out against a person without that person's consent.
The act may be carried out by physical force, coercion, abuse of authority, or against a person who is incapable of giving valid consent, such as one who is unconscious, incapacitated, has an intellectual disability or is below the legal age of consent.
Some countries or jurisdictions differentiate between rape and sexual assault by defining rape as involving penile penetration of the vagina, or solely penetration involving the penis, while other types of non-consensual sexual activity are called sexual assault.
Victims of rape or sexual assault come from a wide range of genders, ages, sexual orientations, ethnicitities, geographical locations, cultures and degrees of impairment or disability.
