Interesting. I've heard that women can often be aroused without even realizing it. I wasn't aware that they could straight up climax in the same fashion.
So much of female sexuality is either emotional or psychological, rather than mechanical. It's kind of an odd thing to wrap your head around.
I think, partly, it's the plausible deniability of female arousal, even for the woman herself, in a society where arousal is still seen as embarrassing, especially for pubescents, who may experience it at random and at times they would rather not. It's hard to deny an erection. Female arousal, more so.
Another is that there is just such wide variation in ways women can orgasm, even from the same body part. If you start off with something at the higher end of the intensity range, you may not realize the lower intensity hills are still, well, hills. That's what the woman in the OP article said is probably what happened to her.
If you start out lower, on the other hand, being on one's way to a higher intensity orgasm can almost be chaotic or frightening. A lot of women back off it before it happens.
Of course, women do suffer more in the libido department from survival stress, as men suffer more from physical maladies. Personally, although I am less susceptible than it seems most are, if something extreme enough happens to me, I lose the ability to orgasm completely for perhaps a week or two. But that takes some serious mayhem, grief, and suffering. It's not an "I had a ****ty day at work" kind of thing, or even an "I'm really sick today" kind of thing.
Makes sense. If things feel unsafe, getting closer is probably a bad call, and what brings people closer than orgasm?
But for either sex, most of orgasm really is in the brain. Guys can orgasm without any touch, without an erection, or even without ejaculation. It's considerably less common than de-linked orgasm in women, which is probably another part of why women sometimes don't know they're orgasming, but I've seen the latter two in men on rare occasion.
I once had a "moment" in the middle of class for no readily apparent reason at all when I was about 15. I've been trying to repeat that trick ever since, but it eludes me. :lol:
