I do believe sex before marriage is wrong. Why? Because when you are married to someone, you are showing that you truly love them and want to be with them your entire life - you are devoted to them. When you're just dating, you don't know if it's going to last. You THINK you're in love, and maybe you are, but many times it doesn't work out, and you go on to the next person. Sure, not all marriages work out either, but by getting married, you are showing that you truly feel you love that person enough to (hopefully) spend the rest of your life with them. Dating isn't that way. You "love" one person, but then, actually, you don't...so you break up and start dating someone else. Then that relationship doesn't work. On to the next person. And so you're just sleeping with all these people you're not actually devoted to?? Come on.
