Before there is a "relationship"? Not being a smart aleck: if someone knows you socially before you begin dating, they should have some general idea of where you stand in that regard. For some of the "big" issues in my own life, I generally find it doesn't work well to get hooked up with people who don't already know some things about me. But I am not a fan of online dating, so if that is the route you are going, I really can't help you.
