This exciting new textbook is a compilation of communication case studies that identify the most salient issues regarding communication about sex in relationships. The text provides a basis for developing tangible communication skills, clearer understandings of how interpersonal concepts and theories play into practice, and an examination of ideas not often considered by students. Understanding interpersonal communication elements of sexual relationships is an indispensable component of any model of an overall healthy human sexual development. Moreover, being able to transform such understandings into practice in relationships is a leap toward being able to have the kind of meaningful communication with sexual partners that can potentially improve relationships, encourage safer sex practices, highlight responsible family planning, and work against limits of gendered and cultured expectations related to sex and sexuality. Twenty-one case studies from leading researchers in sexuality from Communication Studies, Sex Science, English and Medicine focus on interpersonal communication, cultural aspects of sexuality, media influences, health, and dark side of communication while building communication skills about these difficult to discuss topics. Each chapter features a series of possible discussion questions and a reference list of the resources that were used as a knowledge-base for composing that case study.
