Excerpt from my latest Sasstrology post (please leave comments on the Sasstrology site):
"The 12th House is where you’re most hidden and, paradoxically, most vulnerable. This is the house of sacrifice, isolation and painful sensitivity. While any natal planet in this house experiences challenges, Venus (especially in a woman’s chart) triggers some difficult relationship patterns. However, these patterns can give you clues on how to deal with your 12th House Venus. While this natal placement can be troublesome in straight and queer relationships, this particular article will examine its impact on opposite sex relationships."
