Just out of curiosity, how feasible do you think this approach might be in practice? I used to work in the Student Life office of my (very liberal and super small) alma mater, and definitely had the sense that certain subgroups within the international student population often struggled to adapt to the new sexual codes of college life, ostensibly even more than their American counterparts. In some sense, that population is simultaneously the ideal target for more robust sex education, yet potentially the least receptive to approaches like Kosenko’s.
A multiple-version approach seems like a reasonable solution at first glance, but I wonder how it would play out when placed in the context of orientation processes that are more broadly aimed at integration and community-building through shared educational experiences — not to mention the foundational concept of college-level educational settings as a place where people of diverse backgrounds can encounter and exchange new, unfamiliar, and potentially uncomfortable ideas in classroom formats designed to facilitate equal and reciprocal interactions. Does that make sense?
