Too shy to talk to my roommate

A whole fucking semester and we are still strangers.

fuck him in the ass when hes asleep

No one will ever call you shy again.

Just be corteous you know the typical stuff. Say hello in the morning, maintain eye contact, smile, slip it in when he's asleep, get him some low rider jeans so you can slip it in whenever he sits down or bends over. You know just typical good neightbor friendly person type of shit. That should help your relationship a shitload and you might have a bunch of shit on your cock if he doesn't wipe.....Remind him to wipe too. That's what a good neighbor does.
