Trans men who have sex with men (cisgender or transgender) have been greatly overlooked in HIV testing efforts. The belief that transmen only date cisgender women is myth. The reality is that trans men engage in a diverse range of sexual behaviors. While the reported prevalence among trans men overall is low, we know that TMSM are engaging in sexual activities that are known to increase one’s risk for HIV acquisition. This breakout session will increase provider capacity to conduct effective sexual health assessments and to provide culturally responsive HIV services tailored to address the prevention and treatment needs unique to TMSM. This will be an interactive presentation that will cover diversity of sexual orientation and expression in TMSM, culturally responsive sexual health assessments, partner services, sex negotiation, and prevention with TMSM.
