There is a concern that the bodies that are shown to us in sexually explicit media are changing what we think is beautiful, are making us anxious and depressed, and even are pushing us to engage in self-harmful behavior. This chapter provides theoretical explanations for why pornography images could impair health and reviews studies that have investigated this question. The chapter covers findings related to pubic hair removal, labiaplasty, vulva acceptance, men’s genital dissatisfaction, satisfaction with body shape and size, self-esteem and self-confidence, and expectations of partners’ bodies. The chapter concludes that pornography likely harms some people’s self-image, and for a minority of those who are harmed, it drives them to extreme behaviors and has mental health consequences. For the majority, pornography either has no effect, improves how they feel about their bodies, or underscores the body-related attitudes that they have already acquired from non-sexually-explicit media.
