Is premarital really a sin?

Well, I am an atheist, BUT when I was a Christian, I strongly viewed premarital as a sin because in the Bible, it states that you have you be married in order to have . Whether you love someone or not is not the question, but it is what you do with your feelings that counts. I am not a virgin either, but I used to strongly value my virginity when I was one. Premarital is considered to be a sin because according to the Bible, premarital means that one is not strong enough to hold the urges and does not necessarily mean love. Other sex sins include sex, adultery, sex with animals, oral and sex, and even the withdrawal method is considered to be a sin because, according to the Bible, those ways mean that sex is used just for pleasure, rather than biologically producing children. Of course, there are sins worse than premarital sex. What you do is something you should choose. Consider the possible results of premarital sex. I myself did not wait until marriage to have sex, but I do believe that it is important to lose your virginity to someone that you care for.
