Brief summary

The goal of this quasi-experimental, community intervention is to reduce HIV sexual risk among Latino immigrant bisexual men or men who have sex with men. The main questions the study aims to answer are: Does the intervention improve sexual risk behaviors? Does the intervention increase self-esteem and social support? Are self-esteem and social support mediators in the link between the intervention and sexual risk? Researchers will compare information from the intervention versus control participants to answer the above questions. Participants in the intervention arm will take part in: * One day-long (8-hour) group retreat. * Weekly discussion groups. * Community events and civic engagement activities. * Prevention counseling. Participants in the control arm will not be part of any activity.
