A single male college student

You are a 21-year-old man attending college, but mostly you enjoy partying and hanging around friends. You don't have a partner yet. In fact, you have never had sex before.

You find a strange rock while walking. You know it would be classified as metamorphic based on the geology class you were required to take. You hate that class. You pocket the stone absentmindedly and continue walking back to your dorm.
As you walk, you silently think to yourself that you wish it didn't take so long to get back to your dorm. You must have blanked out while walking, because it feels like as soon as you're done thinking that, your dorm room door is in sight. You enter and relax at your computer desk.

You figure you'll have some free time between classes, but you suddenly hear a noise from your door.
