But now we have this story, reported as a bit of a yay/boo/yay by our friend, New Scientist:
Yay: Emmanuele Jannini at the University of L'Aquila in Italy discovered clear anatomical differences between women who claim to have vaginal orgasms triggered by stimulation of the front vaginal wall without any simultaneous stimulation of the clitoris and those who don't.
Boo: Apparently, the key is that women who orgasm during penetrative sex have a thicker area of tissue in the region between the vagina and urethra, meaning that a simple scan could separate the lucky "haves" from the "have-nots."
Yay: Even better, Jannini now has evidence that women who have this thicker tissue can be "taught" to have vaginal orgasms. Ultrasound scans on 30 women uncovered G-spots in just eight of them and when these women were asked if they had vaginal orgasms during sex, only five of them said yes. However, when the remaining three were shown their G-spots on the scan and given advice on how to stimulate it, two of them subsequently "discovered" the joy of vaginal orgasms. "This demonstrated, although in a small sample, the use of [vaginal ultrasound] in teaching the vaginal orgasm," Jannini says.
I knew it! I've been teaching for years and years that internal sensitivity is, or at least can be, a learned response. I don't expect that ultrasound, which is expensive and literally invasive if also harmless and painless is going to become part of Everywoman's sexual fulfillment tool-kit, but how cheering is it to have proof at last? Good news in a bad year, right?
