Women who masturbate don't have to fake an orgasm?

Ladies is the above claim true or false? Don't be prude, pray tell.

According to Jane Greer, Ph.D. New York-based marriage and sex therapist women who masturbate know all their sweet spots and what makes them orgasm. - "They know how much pressure, tempo, speed, lightness, and every single nuance of touch, direct or indirect, on their clitorises they need in order to orgasm." And getting off solo makes it that much more likely that you'll get off when your partner comes into play. "When you know what is exciting and arousing, your partner can enhance it," she said.
