Long post, deal with it or move on.
First things first. Be a friend to her, support her, do NOTHING without discussing it with her and give her space, let her know, like Wyldfire said, that you are an option to help her but don't push yourself into her tramua. Find out the facts FIRST before jumping and go from there.
Second matter. Tiburon, your reply reeks of a sort of cynicism and calousness that ill befits a man. Not to mention a lack of knowledge of how the real world works.
If you haven't had people close to you raped, MOTHERS for example, or lovers, or sisters, or close friends, you simply wouldn't know. So I can't be harsh with you - you could just be ignorant and slightly jaded.
Nothing personal; ignorance is a disease with an easy cure....
Seeking knowledge.
In reality, often when women are raped they do not report it. This has become less the case over the last couple of decades due to an increased assertiveness among American women but in general it still remains true.
Why? Several reasons, some related to the nature of femininity itself - remember, that elusive state that the Feminazis seek to strangle. Women, being intensely *social* and hyper socialized beings, have an acute awareness of the concept of *shame* (when sober, anyway). Shame, as opposed to guilt, is an external behavioral mechanism. We feel shame before others. We feel guilt in ourselves.
Shame is a reason for the "anti-slut defense" that even very sexual women will put up. A girl could drop trou in an empty subway car for the right guy if it felt "meant to be" the whole while protesting that she's not a slut "and would never normally do this." This is because THE SOCIETY OF WOMEN IS SELF POLICING. Women's judgements between peers are taken very seriously in their networks. (Pook touches on this subject... a lot).
In spite of what Pook and Deep Dish say (two DJs who seem to have sharp understandings of the essence of women, Player Supreme too) you've gotta try to understand women at least a bit. Yeah, she's made to be loved not understood but this is no excuse for slacking and rolling in ignorance.
Rape = SHAME in some women's minds. This is actually universal, in most cultures particularly non feminized, Virile, traditional ones, Rape is a matter of *honor*, honor and shame. This is why in so many cultures, from Africa to the mid east to the orient Rape is dealt with quietly in the tribe or family and village, only if it becomes publically known is violent retribution often sought.
To admit to being raped is to bring up questions like "did I deserve it?" "what did I do to cause it?" and so on. Women are raised with higher degrees of internal modesty (though this is RAPIDLY vanishing nowdays) regarding her sexual functions in public society. For example, in private she may be a nympho, with her gal friends conversation may be dirtier than a boatload of drunk sailors, but in PUBLIC she maintains a very real mask, a face. It's not a front, its how she's socialised. Why do you think getting her drunk helps you bang her? Booze relaxes social barriers letting her natural lust be more freely expressed. You isolate her, magic happens. This is an example
Now, RAPE is a brutal thrust at the essence of her physical womenhood. This trips all insecurities about her being, her sex, her personhood. This sh1te she wants to keep PRIVATE.
And this applies to guys too. Tell me that if someone butt-rapes you you would sing like a bird and tell all and sundry. Whatever. Most guys would bury this crap DEEP down and get on with their lives scared and angry but you'd deal with it. Guilt and Shame would come into play. Shame is a function men and women both feel. Rape is tramuatic for both men and women and deep attacks to the core of our genders. Rape a man up his arse and you attack his virility and manhood. Rape a woman and likewise you attack her womanhood and the barriers around her sex.
There's too much jaded cynicism on this board. It's healthy, when I first started reading sosuave, 2 years ago, I didn't even join at first because I didn't want to post. Too much anger and bitterness at chicks. Get over it, it's better for you in the long run.
