NUMBER  THREE :Do you know where you stand in  the relationship
 This one is huge. Sex can change your relationship in pretty drastic ways.
So it's important to know where you stand. Is it a serious relationship? Or are you two more friends than lovers? You need to make sure that both you, and your partner, are on the same page. If one person ends up falling in love, and the other isn't feeling it, it can lead to serious emotional and psychological distress. And if you two are friends with benefits, ask yourself if you're willing to lose that person as a friend. Because, believe us-it can happen.
