Sexual dysfunction in women lies largely in the brain, says a new study coming out of Stanford; 40% of women lack the mental arousal despite the physical ability to do so, as observed while testing the brain and "objectively observing the gentials" while the test subject viewed women's sporting events interspersed with snippets of erotic movies - which sounds like the awesomest application of the Ludovico Technique ever. While they don't say exactly what the brain issue is, there seems to be a connection to how aware a woman is of her body's sexual arousal, which means that relaxation and release may be more important than some hormone or blood-flow issue.
