If you are convinced that childbirth can be nothing other than excruciatingly painful, well then, you are likely to have an excruciatingly painful childbirth. It's a self-fulfilling prophecy.

Orgasmic Birth is a documentary that examines the sexual and intimate nature of birth and the powerful role it plays in women's lives when they are permitted to experience it. This documentary asks viewers to reexamine everything they thought they knew about giving birth and the potential it holds.
