Maybe so but people's feelings can change anyway. My whole point is that just because you are married doesn't mean you'll be with that person for the rest of your life. People who can emotionally handle having sex without marriage aren't doing anything wrong, as long as they aren't cheating. Maybe it's not the lifestyle for certain people like you, but it's not morally wrong. It's just not your cup of tea. Religions like Christianity can teach people to be incredibly judgmental.
