In fact, if you really want a story that's got it all, look up the story of Tamar. It features incest, prostitution, extortion, and a moderately graphic description of primitive birth control. She is also one of only three women (other than the Virgin Mary) mentioned in the lineage of Jesus. The other two are Rahab, a prostitute turned informant in Jericho, and Ruth, a pagan who, through sheer determination, worked her way into Jewish society by way of her mother-in-law.

People have been arrested for translating "The Song of Solomon."
