Inconsistent condom use was more prevalent among men who have sex with men who said they accept having sex without using a condom when trusting their sexual partner (84.2%, p<0.0001). Trust in a sexual partner had a strong association with inconsistent condom use during last anal intercourse among all men who have sex with men (adjusted prevalence ratio (PRa) of 1.73, 95%CI 1.25-2.40, p<0.0001). This association remains statistically significant in our stratified analysis among single/separated/widowed men who have sex with men (PRa=1.93, 95%CI 1.44-2.60, p<0.0001) and among men who have sex with men who are married/live together (PRa=1.31, 95%CI 1.11-1.77, p=0.045), indicating that trust can be experienced in different relationship contexts, not only with main or steady partners, such as a husband or boyfriend.</p><p><strong>Conclusion: </strong>Trust plays an important role in sexual behavior among men who have sex with men, and it is related to a higher prevalence of inconsistent condom use.
