<p>Brown has co-ed dorms. But I think only if you're gay.</p>
<p>Dartmouth is considering designating some rooms co-ed starting next year.</p>
<p>University of Rochester was one of the first to offer</p>
<p>Columbia is almost completely co-ed. I think only a few floors on one building are not.</p>
<p>Do you mean that the rooms are co-ed? So a boy would have a girl as his roommate? I don't think I'd be comfortable with rooming with a complete stranger who's a boy. What about when you change and stuff?</p>
<p>I think this housing option is definitely optional.</p>
