Abstract
OBJECTIVE: This study aimed to examine sexual desire among men who have sex with men (MSM) in the Czech Republic using the Sexual Desire Inventory-2 (SDI-2) and to identify differences based on sociodemographic and behavioral characteristics. METHODS: Data were collected via an online survey between 2021 and 2022. The SDI-2 was administered to 410 MSM aged 18 to 60 (M = 29.7) and recruited through social media and community outreach. The questionnaire included dyadic and solitary sexual desire subscales, as well as sociodemographic and behavioral variables (e.g., sexual preference, HIV status, education level, and frequency of sexual activity). Statistical analyses included ANOVA, Pearson correlations, and effect size calculations (η(2)). RESULTS: MSM reporting sexual attraction to both men and women had the highest total SDI-2 scores, followed by those attracted exclusively to men. Respondents attracted solely to women scored significantly lower. Dyadic sexual desire was positively associated with being in a relationship and a higher frequency of sexual activity, while solitary sexual desire correlated with younger age and more frequent masturbation. HIV-positive participants reported significantly lower scores across both subscales. Education level showed a significant effect, with the highest sexual desire found among those with incomplete primary education. CONCLUSIONS: A combination of behavioral and sociodemographic variables influences sexual desire in MSM. These findings provide new insight into sexual motivation among Czech MSM and underscore the importance of inclusive sexual health interventions. Further cross-cultural studies using the SDI-2 are encouraged.
