Background and purpose: Sexual self-disclosure as a psychosocial sense is defined as individual’s interpretation on how to express feelings in marital relationships. This study aimed at determining the predictors of female sexual self-disclosure in Tehran.

Materials and methods: In this cross-sectional study, 200 married women in Tehran were selected by convenience sampling. Hurlbert Index of Sexual Desire and a demographic questionnaire were administered. Data was analyzed in SPSS V.20 applying descriptive and inferential statistics including Pearson, Spearman, ANOVA, and linear regression.

Results: The average score for sexual self-disclosure was 56.16±14.60. Some variables including the participant’s age, age of husband, duration of marriage, and time of last delivery were found to have significant inverse correlation with sexual self-disclosure. In multivariate model, marital life, the interest level in spouse, and duration of marriage were significant predictors of sexual self-disclosure.

Conclusion: Sexual self-disclosure was found to be low in this study. It is believed that marital life, duration of marriage, and interest level in spouse play important roles in women's sexual self-disclosure. Communication skills are suggested to be taught in premarital classes to enhance sexual self-disclosure, satisfaction and happiness in marriage.
