Excerpt from my latest Sasstrology post (please leave comments on the Sasstrology site).
"Venus and the Moon are the two primary significators of female energy in the natal chart. In a straight man’s chart, they describe two sides of his romantic partnerships with women. His Venus represents the type of woman he’s attracted to, and his Moon represents the type of woman he is comfortable with. To put it another way, Venus describes the woman he wants, and his Moon describes the woman he needs. These factors will be modified by the rest of his chart (especially his 7th House). When one or both of these planets form a hard aspect (conjunction, square or opposition) to his Saturn, it can significantly impact his relationships (in very different ways)."
