<sec> <title>BACKGROUND</title> Transgender men and transmasculine people who have sex with men (TMSM) are at elevated risk for HIV acquisition, have unmet HIV prevention needs, and have low uptake of antiretroviral pre-exposure prophylaxis (PrEP). To our knowledge, there are no published efficacious behavioral interventions to decrease HIV risk specifically for TMSM; this includes peer-delivered strategies that demonstrate high acceptability in this population. </sec> <sec> <title>OBJECTIVE</ti…
