Surprisingly informative, compassionate and factual. Davidson's research reveals the evidence from experts, including American Psychological Association researchers that homosexuality is caused by post-natal factors including, but not only, insufficient bonding and affirmation from members of the same sex through childhood and pre-puberty. She interviewed ex-gays from six continents and includes their first person narratives of their journeys to achieving heterosexuality. Most of them followed protocols by authentic, mainstream reparative therapists who belong to the Alliance for Therapeutic Choice and Scientific Integrity. There's not one story of shaming, shocking or weird nudist practices in out of the way camps. It's all mainstream talk therapy. The stories all point out that sex does not cure a childhood wound, that achieving heterosexuality is a developmental milestone (usually achieved by age 11) and that latent heterosexuality occurs because of the willingness of an individual to delve deeper into his/her psychological need of belonging and being appreciated by his same-sex gender community. The book sort of answers the question about sexual fluidity in the sense that sexuality can change into heterosexuality.
