It most often develops in adults over the age of 40. It is also more common in women and in people with a family history. However, it can occur at any age due to injury or other joint-related diseases such as gout or rheumatoid arthritis. As Stephen Arroyo once said in a conference I attended, "After all, Virgo can be an earth sign." Earth signs are sensual, grounded, of the body. The difference for Virgo is always that sex must serve an increased purpose. As Virgo sifts the wheat, separating the chaff from your lifegiving grain, therefore it sifts its human relations so they must be lifegiving. Virgo sexuality have to be dedicated to something greater than itself. It must be for that sacred, focused on the goddess principle. What we choosing a lump sum may be the image from the strong woman standing proud in their sexuality, deploying it to offer the divine by sharing it and it is bounty with other people, teaching through her bliss and ecstasy. When this image is lost to us being a culture, most are lost concerning their particular definition of themselves, also it hurts us all by limiting our perceptions of our own sexuality as well as higher purpose.
