An excerpt:
Rape is not always violent. Some survivors surrender to protect themselves or their loved ones. Some are intoxicated, drugged, physically or mentally incapacitated, or in a position without power. Some (doubly horribly) are children. Rape does not always include penile penetration. Some rapists are married to their victims. Some rapists are women. Some women rape men. And sometimes, in the middle of an act that is always a violation, a rape survivor will experience increasingly intense physical sensations leading to climax – an orgasm.
Judges, juries, prosecutors, all in the legal system need to be aware. An orgasm during rape does not imply consent. In fact, it only makes the shame greater.
Worth your time.
