Premarital sex?

What are some reasons why premarital sex is not wrong, and does it state anywhere in the bible that premarital sex is wrong or is it just how people interpreted it? I'm doing persuasive essay on this and i need some reasons to support my claim(that premarital sex is not all that bad)

I am an atheist, for I see the Bible is full of errors. I never plan to marry, but I have sex every day. I am an adult, and my 6 lovers are adults. I have never raped anyone or made false promises to a gal. One must use some logic in any matter. The Bible has some quite extreme rules. One of the worst is Jesus said it is as sinful to look lustfully at a woman as to commit adultery with her. Well, a normal man thinks about sex much of the time. If a man isn't thinking about possible sex with most attractive ladies he encounters, he is thinking about sex with other men. Such extreme stuff is designed to make one feel guilty about normal impulses, and one is supposed to pay preachers to relieve that guilt. It is an obvious con game that preachers use to buy Rolexes and Cadillacs, as Robert S. DeRopps said.

I do not find that premarital sex is wrong. I am an Atheist and do not follow any bible teachings. I had sex before I was married. Not a big deal. The only thing is that if a person decides to have it, that it be an intelligent decision. Being too young or ill prepared, can lead to STD's and unwanted pregnancies. Sex is part of our being human. It is instinctual. Repressing it with religion is ridiculous.

Here are two sites that have different looks at it for you,
