Personally, for me, I'd like to see at least 4 or 5 dates before we even get to that topic. They don't have to be "official dates" per se, but I do think spending time with someone before making that decision is important. I guess I look at it from this perspective, the first couple of dates, your both on your best behavior and you really don't get a sense of someone, except on the surface. Once you get past that stage, and you can both be comfortable with each other, that's when you really get a sense of who someone is...how they are with their guard down.
