Former New York City Ballet dancer Toni Bentley detailed her spiritual awakening through anal sex in The Surrender: An Erotic Memoir. “I am sitting on the threshold. Perhaps this is the final paradox of God’s paradoxical machinations: my ass is my very own back door to heaven. The Pearly Gates are closer than you think,” she wrote. Some people do yoga or visit a therapist, but for Bentley, “emancipation through the back door” was the only thing that healed a lifetime of psychosexual problems and daddy issues.
