People should understand that they are in college and that you both have to deal with privacy issues.  Having sex in a dorm room all depends on who the two roommates are.  I would respect my roommates privacy if they wanted to use the room, because i would want them to do the same thing to me.  A roommate that is not willing to let their roommate use the room for at least an hour is very selfish.  The University establishing rules about it, is completely wrong.  The roommates should come to some sort of agreement on their own, even if they have to go somewhere else to have sex.  Personally if I did not have anywhere else to go, I would go to my dorm room, but everyone should have a place to go, especially if they know their roommate will go ballistic about the whole situation.  I think the school is going to have a tough time making this rule stick, simply because the students will argue that it is their room, they're paying for it, and they can do what they want in it regarding sexual activities.
