I loved how we talked about sex as a means to bring a couple closer together. The world teaches you if you love someone, you should demonstrate that love by having sex. Once I joined the church I learned that is not true, but then I was confused as to what purpose sex had. I knew of course it was to procreate. It was cool to learn about how it's one of the strongest ways to bring your relationship closer together. That may be one reasons it's not good to do before you are married. It reminds me of that chart. Your touch can not be above your know. You don't want to rely and trust someone you don't know. When you have physical intimacy you can create emotional bonds that are not supposed to be there before you are married. I've always been worried about how much information I am required to disclose to my future spouse. I had always thought that once you are baptized everything from your past is erased in the eyes of the Savior, so why should anyone have to know. I was surprised while in class when we talked about being honest. I never had thought about it before. Then after talking to a really good friend I realized how important it was to him to know everything about his wife before he marries her, I realized my future spouse may feel the same way.
