Attention has grown around narratives of sexual harassment in recent years, yet a significant number of stories remain untold, particularly those of male victims or survivors. While the reasons behind these unspoken or delayed disclosures vary worldwide, the present study examines the factors influencing men, born and raised in Iran, to remain silent rather than disclose incidents of childhood sexual harassment until adulthood, and the impact of this silence on their lives. Five Iranian men, ranging in age from 28 to 40, participated in this qualitative study and had their experiences as victims interviewed. The consequences of non-disclosure are further investigated in the study, with a particular focus on mental health. Participants identified societal judgment and labeling as major reasons for their hesitation to speak out, fearing persistent stigma and the possibility of becoming targets for further abuse. Lack of sex education, cultural taboos surrounding sex, and proper mental health guidance are other significant concerns that have been mentioned. These experiences had profound effects on the participants' mental health, manifesting as depression, anxiety, and suicidal thoughts and attempts both in childhood and adulthood. The findings underscore how societal expectations, gender roles, and stereotypes perpetuated by patriarchal norms contribute to the reluctance of Iranian men to disclose incidents of sexual harassment and seek assistance.
