This study aimed to identify the factors that interfere in maintaining safe sex. Data were collected through individual interviews with 11 HIV/aids patients living with HIV-negative partners, under clinical treatment at a specialized aids clinic. Analysis was based on Prose analysis by André (1983). The concept of vulnerability was used as a theoretical reference framework. The sexual prevention of HIV/aids for the non infected partner constitutes one of the largest challenges for the serodiscordant couples, because men and women accept condoms differently. The greater motivation towards condom use among serodiscordant couples does not eliminate the difficulties to use them for maintaining safe sex. The serodiscordant couples deserve specific assistance, and the preventive strategies should contemplate the cultural and psychosocial aspects that constitute important aspects of mixed-status partner vulnerability.
