Sorority women are at risk for engaging in unsafe sexual behavior. Fortunately, the positive influence of peer communication about condom use can mitigate the risk these women face. To better understand this communication, this article investigates sorority women’s communication about condom use through focus groups, using the lens of the theory of Communication Privacy Management. The results revealed the criteria for privacy rules sorority women use to negotiate privacy and engage in comfortable communication with other women in the sorority. The analysis also revealed an external privacy boundary; the women sought to maintain a good reputation for their social group, and followed explicit and implicit privacy management rules to do so. The implications for this study include better understanding of the personal and collective boundaries of privacy management, and improvements in sorority and college student sexual health programs.
