Biastophilia

Biastophilia (from Greek biastes, "rape" + -philia) and its Latin language-derived counterpart, raptophilia (from Latin rapere, "to seize"), also paraphilic rape, refer to a paraphilia in which sexual arousal is dependent on, or is responsive to, the act of assaulting an unconsenting person, especially a stranger.

Some dictionaries consider the terms synonymous, while others distinguish raptophilia as the paraphilia in which sexual arousal is responsive to actually raping the victim.

The source of the arousal in these paraphilias is the terrified resistance to the assault, and in this respect it is considered to be a form of sexual sadism.

Biastophilia is accepted as potentially lethal, other such paraphilias including, but not being limited to asphyxiophilia, autassassinophilia, hybristophilia, kleptophilia and chremastistophilia.
