<p>I don’t understand why you can’t simply tell your roommate that your dorm room is not a Motel 6. There are ground rules that you both need to agree to, since you both pay for and must live in the room:</p>
<ul>

<li>no sexual activity, including make-out sessions.</li>
<li>any other ground rules you two need to mutually agree on.</li>
</ul>
