It was all about the clit on Tuesday, when Oprah had her go-to gal on lady issues โ€” author and gyno Dr. Christine Northrup โ€” on as a guest to discuss women's health. Dr. Northrup is different in her approach from Dr. Oz. He's scientific and very "just the facts ma'm," while she's into nurturing your soul, empowerment and acceptance. She seemed slightly to be leaning a little too much toward the new age-y side, until we got to the segment that revealed how progressive she is about sexuality and masturbation. (Although she doesn't like the word "masturbation" and would prefer instead to use "self-cultivation.")
