<p>In college, my sons live in suites where they have their own rooms. They have very little to do with/rarely see their suitemates, so it probably wouldn’t matter if those were male or female. Perhaps the suite would smell better with female residents? 
But I don’t want my daughters living with any guy that isn’t married to them.
Someone said proximity is not a good way to pick a romantic partner. IMO, it is one of the most common ways. I lived with a couple male room/housemates when I was young. In the classic double dormroom/bathroom down the hall setup, my roommate’s boyfriend lived with us for most of a year. Yes, I would ask him to “turn around” when I got dressed, and he was very good about that (he never teased me or tried to look. . .) Another time I shared a house with a man who had a girlfriend. Eventually both of these guys, whom I considered “close friends,” wanted to be more than friends. Cringe–there were a few awkward moments. We remained friends, but. . .something changed. What makes you attracted to someone? Spending a lot of time in close quarters, conversation, getting to know each other, etc. Even if the person is romantically involved with someone else, it is hard not to imagine that room/housemate as a potential partner. And I think it is harder for males to NOT be attracted/develop feelings for a woman that they are living with.( IMO a lot of girls are naive/clueless about this.) Which is why I wouldn’t want my daughters living with guys. “Let’s just be friends. . .” It is unnatural. It just doesn’t work, in my experience. Too much potential for drama.</p>
