The REAL World

So I'm on vacation w/ my friend and i met some of her friends. There are two beds in the room I claimed and a bathroom as well. Me (single) and my friend's guy friend are sharing this room. Long story short, we've had sex since the beginning of this trip. I feel sort of cliche though...I can't be the only one who's ever became FWB's with a temporary roommate of the opposite sex...right?
