Background: Potential problems among couples can negatively impact the lives of the family. Objectives: The present study aimed to investigate the relationship between sensation-seeking, gender role conflict, and novelty-seeking in married men with the mediating role of sexual function. Methods: This was a correlational study performed by path analysis. The statistical population comprised all married men in Bushehr (Iran) who visited marriage counseling centers in 2020. A total of 384 married men were selected as the sample using convenience sampling. The research tools included the Zuckerman Sensation-seeking Scale-V, the Gender Role Conflict Scale, Justification for Extramarital Involvement Questionnaire (JEIQ), and the Sexual Self-Efficacy Scale-Erectile Functioning (SSES-E). Data were analyzed by the Pearson correlation method and structural equation modeling (SEM). Results: Based on demographic results, the mean (SD) of the age of participants was 45.29 (6.37) years. The results revealed a significant relationship between sensation-seeking and sexual function, and between sensation and novelty-seeking in men (p<0.001). There was also a causal relationship between sensationseeking and novelty-seeking mediated by sexual function in men (P=0.004). The findings also revealed a significant relationship between gender role conflict and sexual function as well as novelty-seeking (p<0.001), and a significant relationship between gender role conflict and novelty-seeking mediated by sexual function in men (P=0.012). Conclusion:According to the results, the proposed model had adequate fitness. Male sensation-seeking and gender role conflict lead to numerous problems for men, spouses, the family, and society.

This study aimed to investigate the association of emotional and cognitive intimacy with promiscuity through the mediating role of attitude towards infidelity in married men. Methods: This applied descriptive study had a correlational design and adopted the structural equation modeling method. The statistical population included all married men in Bushehr (Iran) who visited marriage counseling centers in 2020. A total of 384 married men were selected as the sample using convenience sampling. The research tools included the Personal Assessment of Intimacy in Relationships, Attitudes towards Infidelity Scale, and the Justifications for Extramarital Relationships. Data were analyzed via the Pearson correlation method and structural equation modeling. SPSS version-24 and AMOS-24 were further used for analyzing the data. Results: The results indicated that there was a direct association between emotional intimacy and attitude towards infidelity (β=0.18, P=0.001), cognitive intimacy and attitude towards infidelity (β=-0.62, P=0.001), emotional intimacy and promiscuity (β=0.11, P=0.014), attitude towards infidelity and promiscuity (β=0.68, P=0.001), but there was no a significant association between cognitive intimacy and promiscuity. The findings also revealed a significant relationship of emotional (β=0.19, P=0.009) and cognitive (β=-0.39, P=0.007) intimacy and promiscuity with mediating role of attitude towards infidelity in men. Conclusion: In general, this study revealed that emotional-cognitive intimacy is a predictor of promiscuity. Therefore, the findings can contribute to studies that lead to marital stability.
