A cross-sectional exploratory study implemented in June 2015 in Zahedan, the capital city of Sistan-va-Baluchestan Province, located in the southeast of Iran.<br> <strong>Methods: </strong>Using convenient sampling method, from among student of two large universities in Zahedan, 134 students 18 to 22 years old, accepted invitation for filling a self-administered anonymized questionnaire containing, 8 semi-closed questions about sexual issues.<br> <strong>Results: </strong>44.9% of women and 41.6% of men mentioned one of their friends as their tutors. While 42.0% of women mentioned their mothers as one of their tutors, only 18.8% of them believed that more than 50% of their sexual knowledge came from their mothers. 23.1% of male participants and 36.2% of female ones alleged to know personally people of their own ages who had been subjected to sexual abuse or harassment earlier in their life.<br> <strong>Conclusion: </strong>In Iran, educating sexual issues to adolescents is badly in need of organization and management. While the rule of a committed extra-family tutor (e.g. an officially appointed school teacher) might not be considered a solution, parents have to be prompted for filling the gap.</span></span><br> &nbsp;</div> Adolescence, STDs, Assumptions of sex research, College students, Education 234 244 http://jhehp.zums.ac.ir/browse.php?a_code=A-10-130-1&slc_lang=en&sid=1 Shahrokh Izadi izadish@yahoo.com 100319475328460010046 100319475328460010046 Yes Health Promotion Research Centre, School of Public Health, Zahedan University of Medical Sciences, Zahedan, Iran.
