Charles Moser, PhD, MD is sex educator, sex researcher, clinical sexologist, and sexual medicine physician, who practices in San Francisco. He has been a pioneer in the creation of and the practice of the new medical specialty of Sexual Medicine - The Medical Aspects of Sexual Concerns and Sexual Aspects of Medical Concerns. I focus on patients with any type of sexual concern, HIV+ patients, people struggling with sexual dysfunctions or looking to enhance their functioning, those who identify as a sexual or gender minority, those who practice (or hope to practice) an alternative sexual or relationship lifestyle, and those who engage in nonconforming sexual or gender behaviors.
