On her knees : memoir of a prayerful Jezebel / Brenda Marie Davies.

Enhanced descriptions from Syndetics:

"The problem was, because Purity is an idol (a validated and worshiped idol), I didn't know who or what I'd be without my totem. My Christianity depended on Purity."

Going to a conservative Christian church when she was young, Brenda Marie Davies heard a consistent message-- save yourself for marriage --that instilled in her fear and shame about sex. But after moving to Los Angeles at nineteen and finding herself suddenly exposed to a world far outside her comfort zone, she was forced to wrestle with the power and perversity of Christian purity culture.

On Her Knees chronicles Brenda's spiritual journey over the course of a decade in LA, through marriage, divorce, unlikely friendship, and sexual exploration. Through it all, she began tearing down the false idol of purity while refusing to abandon her faith.

Told with raw honesty, sans obligatory shame, this is a story for anyone who wonders if it's possible to love God without fearing sex, in all its shades of grey.
