<p>Fair point, jonri. In college, though, I tended to know women in bunches, so it would be pretty rare for me to know a woman and not know her roommates. And everybody pretty much knew everybody else’s business – certainly who was sleeping with whom on a regular basis, and where, unless they went to a lot of trouble to hide things (which would NOT have included performing with a roommate present).</p>
<p>Also, thinking about it – my college didn’t have any one-room doubles. The most common configurations were three-room quads (two bedrooms and a common room), two-room doubles, and singles. People shared bedrooms in the quads, but there was usually a couch in the common room that would be sleepable in a pinch, and there were also satellite libraries in the dorms that were open all night and had comfy couches. So it wasn’t all that hard to find someplace else to sleep if your bedroom was going to be in use. Net, probably something like 3/4ths of the students living in the dorms had their own bedrooms, so for most couples there was a place to go that didn’t pose this problem. And the people for whom it came up most often – freshmen – were not, really, as promiscuous as their reputation.</p>
