This blog, which I recommend reading, makes a good point that some of the causes of modern FSD (Female Sexual Dysfunction) are sociocultural. To quote:
She also makes a smart review of the attitudes toward women's sexuality during the middle ages and Victorian Era, providing a chilling measure of context. Ultimately, research on multiple fronts will be necessary. Now, who'll fund it?
Again, I offer this link, to an article reviewing several researchers' theories of the human sexual response cycle.
