Excerpt from my latest Sasstrology article (please leave comments on the Sasstrology site):
"There’s no doubt that the Sun is important in relationships. But it’s such a major player (to the point of being a cliché) that it’s sometimes disregarded in favor of the Moon, Venus, Mars, Saturn, etc. But don’t be put off by its association with Sun sign astrology. The Sun represents your purpose, ego and conscious will. It will always be a primary player in relationships. The aspects that your Sun makes to your other planets describe how you integrate its energy. Sun conjunct Venus suggests an abundance of charm with the primary desire to love and be loved. Sun trine Saturn suggests a steady flow of sober responsibility and commitment. But what if your Sun is unaspected?"
