it depends i think. whenever the both of you feel its ok to become exlusive i guess..

and what bigbear said reminded me of when i was younger.... i had just gotten out of a 3 and a half year relationship when i was 17 and was un aware that there was a difference between just dating, being a couple and friends with benefits lol (what? that guy had me sheltered from the world! besides, all my friends were loners and didnt go out much so no one was theer to inform me of that stuff) anyways, i met this guy and we hooked up and i assumed he was my bf.... so i was goin around tellin everyone we were together and all... that was embarrassing when i found out we weren't lol. *feels like a dork*
