Many years ago I was dating a girl. One evening things between us were proceeding as they naturally do between two people who are attracted to each other. Things were quite hot and we were down to our underwear. I was removing her panties.
"Stop" she said.
I did. We lay beside each other, eyes into eyes. A very intimate moment. She finished undressing me, with some unmentionable activity. I started to reciprocate.
"Stop" she said.
It was our 6th date, we hadn't had sex yet. I don't believe there is value in rushing into sex so I wasn't concerned or frustrated except as to a desire to know what her thoughts were in that moment. I was a bit worried she might have suffered abuse. So we cooled off shared a smoke. We talked. I waited and listened. As I expected she brought the conversation back to her earlier stop preference. This is the part of the memory that is the most vivid.
She said, "I wanted you to, you know, go for it."
"But you were saying stop."
She squirmed a bit and put her hair behind her ear. "Yeah. I know. But I didn't want you to."
I didn't have words then. She broke it off a few days later. I never discovered if she was abused or not.
For years I've thought about this. I've gone through the whole gamut of reactions from confusion, then disgust, then acceptance. But never real understanding. Why desire forced sex? Do women want to be raped? Is this why some women place themselves in situations where a ethically bankrupt man can take advantage? If some women seek forced sex, why?
I don't have answers to these questions.
According to Psychology Today, "From 1973 through 2008, nine surveys of women's rape fantasies have been published. They show that about four in 10 women admit having them (31 to 57 percent) with a median frequency of about once a month. Actual prevalence of rape fantasies is probably higher because women may not feel comfortable admitting them." 
I can almost understand or at least accept the idea of "I'm being forced and I enjoy it" fantasies. I presume that this is part of the BDSM culture. But the fantasy of "I'm being forced and I hate it" IS RAPE and is very prevalent in women. The degree to which I am appalled cannot be conveyed without strong euphemism and body language.
Dr. Michael J. Bader, author of Arousal: The Secret Logic of Sexual Fantasies, writes: "It is quite common that children who were abused grow up and develop sexual fantasies loosely based on their abuse. ... The adult indulging in a fantasy of sexual surrender or abasement is actually saying to her or himself: 'I'm recreating a terrifying or traumatic scene, but this time I'm in control because I'm scripting the scene ...'" 
The figures for rape fantasy and and childhood sexual assault don't really line up.  But on the other hand this kind of data is likely difficult to accurately obtain.
What influences a woman's desire for forced sex? What do you think the root causes of that fantasy are? Is indulging a woman's forced sex fantasy in a consensual way harmful to her or to society? Are there women who seek to be raped? I have opinions on this - I want to hear yours.
