title: [Implications of AIDS on the biography of men with homoerotics practices in Mexico City].
abstract: OBJECTIVE
  To determine the changes in the biography of men with homoerotic practices in the times of AIDS.
  
  
  METHODS
  A retrospective (biographical) survey was administered during the first semester of 2006 to 250 gay/homosexual men in Mexico City. Based on this survey, 633 couple stories, taking place in different time periods, were reconstructed. In addition, taking into account the epidemiologic behavior of HIV-AIDS in Mexico, three couple cohorts were defined as: "before AIDS" 1970-1984; period of "exponential growth" 1985-1995; and "stabilization period" 1996-2005. The 633 stories are distributed along these time-frames, taking the starting date of each relationship as the criterion.
  
  
  RESULTS
  During the period of this study, less sexual exclusivity and shorter duration of sexual relationships were found among couple cohorts. The latter process has been documented elsewhere and is called of "sexual distension".
  
  
  CONCLUSIONS
  The research allows for understanding the social history of the epidemic and as well as its implications for HIV-AIDS prevention policies.
