My son was a closeted gay. Came out in college. By chance alone he had a single his first year, and kept that in soph year. Junior year he spent abroad, senior year he lived off campus with another student (not in a relationship). I think a lot of the housing choice depends on the personality of the kid – apart from sexual orientation. We just felt, based his personality, that our son would be better off starting college with his own room in the first year, and then he could make decisions in later years. In retrospect this was a good decision. (BTW, I’m not a mom.)
