Latino men who have sex with men (LMSM) may repress gay, bisexual identities due to internalized homophobia and other sociocultural influences. The impact of Latino traditional gender roles, machismo and caballerismo, have not been examined with LMSM who may or may not identify as gay or bisexual. The purpose of the present study is to examine relations between self-labeled sexual identity, sexual identity developmental status, and traditional gender norms among Latino men who have sex with men (LMSM). The sample consisted of 499 LMSM, (Mage = 30.79), who endorsed engaging in same-sex sexual behavior. Results suggest evidence of concurrent validity of The Measure of Sexual Identity Exploration and Commitment (MoSIEC) with LMSM. Also, men who identified as heterosexual reported relatively higher levels of machismo and caballerismo. Implications for sexual identity development theory and research with LMSM is provided.
