The bible clearly indicates that you shall never have sex before you marry.
No, it doesn't. Your pastor will very clearly tell you not to, but the Bible says no such thing. Jesus said to not be 'sexually immoral' and left it at that. Paul's letters in Corinthians have been interprted as a ban on pre-marital sex, but he was writing those letters to a people known for having wild pagan orgies. They used prostitute priestesses and sex as part of their pagan worship, which is mostly why Paul is so against 'fornication.'
I would challenge anyone who thinks the Bible includes a ban on pre-marital sex to find those words in the actual book. Here is a link to search:

Read the Song of Solomon. Sex, in and of itself, is not bad or dirty. But like anything else, taken to extremes it can be a bad thing. Similar to alcohol, it can be used or abused. Most people can handle it, others destroy their lives with it. It's what you do with it that matters.
