The actress discusses the nature of compromise in a relationship, talking to Caroline Flack, who reveals how she was once tempted to give up her career altogether for the sake of her boyfriend, and Skunk Anansie singer Skin, who talks about her different experiences in relationships with both men and women. Kathy also goes on a chaste date with a gigolo, who claims to offer women freedom from having to compromise during sex, and discusses the neurochemistry of love with an Oxford academic, who stresses that friendship is equally important. Last in the series.
