But what about the fact that, unlike women, men actually seem to like unsolicited vulva photos appearing in their inboxes? Jamie Utt, a sexual violence prevention educator, explained to me via email that men generally react differently to seeing images of a naked body, as they "are not the subjects of a constant, often violent assault of aggressive sexualization" in the way that women are. "If, day in and day out," he wrote, "I was receiving crude sexual advances from a vast array of women all in the context of a wider sexualization of my body in media, I very well may react differently."
This distinction is important. If a woman wants to turn the tables on men by sending them vulva photos, only to find that the men are excited by the pictures, it would be easy to assume that the problem is not with the unsolicited nude images, but that women are too sensitive about receiving them. However, women receive sexually explicit messages from men on a near-constant basis - whether in the form of street or online harassment. So looking for a mate on a dating site becomes yet one more arena where they feel unsafe, and matches become potential perpetrators rather than would-be suitors.
This difference may be why Kerry Quinn's attempt at "revenge porn" had a more positive response than she expected. For many heterosexual men, who are socialized via pornography to enjoy disembodied images of women's naked bodies, the idea of receiving vulva photos in their inbox might be more exciting than threatening.
"In pornography, a woman's body is divorced from her personhood, as women are proverbially dismantled by cameras into a series of close-up shots of genitalia and breasts," Utt wrote. "Any men who have regularly consumed mainstream pornography (which is, frankly, the vast majority of men in the U.S. and comparable countries) are accustomed to disembodied genitalia and have been taught to find it arousing." And while men are not the only people who watch porn for pleasure, most mainstream porn is filmed with the male gaze in mind.
Even if a man were uncomfortable receiving an unsolicited picture of a vulva, would he admit it? Our society teaches heterosexual men that they should want and be primed for sex constantly, ready to have it with almost any woman that shows interest. So they're more likely to respond positively to such images.
But another issue to consider is that some men are survivors of sexual violence, too. A 2005 study found that 16 percent of men had experienced some kind of sexual abuse before the age of 18. So no matter how harmless it might seem to send an unexpected photo of a vagina to a man, it could trigger painful memories for him.
Ultimately, if women want to end the culture of sexual violence that we live in, we have to hold ourselves to the same standard of behavior we want men to abide by. And that means taking consent seriously in all contexts.
