FI and I were laying in bed last night, talking about the wedding, when he turned to me and said, "I think we should stop having sex until the wedding." I looked at him and laughed, because neither of us are religious, nor are we having a religious ceremony. FI has a habit of making jokes and being extremely sarcastic. My family members have a hard time telling if he's being serious or if he's joking. I rolled over and said, "Okay, whatever you say. You won't last a week." He said, "No, I'm serious. I think it would make the wedding night that much more interesting." I was floored. We've been together 6 1/2 years, lived together for 3. I'm not really sure how to handle this. I pray that he's being his usual smartass self, but now I'm starting to question how serious he really is. Anyone have any advice how to approach this?
