Carlin Ross is the business partner of famed sex educator Betty Dodson. Betty Dodson, of course, is the author of the insanely bestselling book Sex for Oneand the consummate orgasm and masturbation guru since the '70s. You might call her a founding mother of women's sexual liberation. I certainly would.
