Much like female erectile response and contrary to popular opinion, male erectile response is involuntary, meaning that a man need not consent for his penis to become erect and be placed in a woman's vagina. Penetration of a man by a woman is possible through use of a strap-on or other object. Rape of a man by a woman could also occur when limited sexual activities are agreed upon and a man's penis is placed in a woman in violation of the limits that had been set. Rape of a man by a woman is thus possible in several ways.
However, male victims of sexual abuse by females often face social, political, and legal double standards. While gender-neutral laws have combated the older perception that rape never occurs to men, and other laws have eliminated the term altogether, the double standards still remain.
