This week, Tim talks to Barry McCarthy, a giant in the field of sex therapy. Dr. McCarthy is a marital and sex therapist, and a tenured professor of psychology at American University. He literally co-wrote the book on erectile issues - "Coping with Erectile Dysfunction" - just one of many books helping men and couples achieve satisfying sex lives. They have a wide-ranging conversation about sexual intimacy, including “good-enough” sex, aging and sexuality, sexual performance, and of course, erectile issues.
