<p>At my college, we’re lucky and have a seperate common room. But I’ve had a similar experience, to a greater degree. When I woke up, they had progressed far beyond making out.</p>
<p>The next morning my other roommate and I (triple) told the guy never to do it again. He apologized, and since then hasn’t. Either in the common room (not an option) or the girl’s room. Tell your roommate that you object to what he’s doing - and hopefully he will listen and go somewhere else. As of now, it sounds like he doesn’t know how big of a problem you have.</p>
