Solomon’s Line on Premarital Sex :

“he stages of a relationship that start with a glance and eventually lead to the honeymoon, the author charges us three times, ‘Do not arouse or awaken love until it pleases,’ or, as paraphrased by Eugene Peterson in The Message, ‘Don’t excite love, don’t stir it up, until the time is ripe, and you’re ready.’ I often point to this book when people, usually young singles, ask me about relationships and pre-marital sex. They want to know, where, exactly, does the Bible talk about pre- or extra-marital sex, when neither partner is married. They know about the adultery prohibitions, and they agree you shouldn’t have sex with someone who is someone else’s spouse. But where does it talk about not having sex if there is no spouse involved? You have two consenting adults, and neither has made any vow to any other person, so it’s not technically adultery. What’s wrong with that? Does the Bible speak to those situations? I like to start with Solomon’s Song, because it celebrates the whole package of the relationship initial attraction, exciting emotions, longing, and sexual intimacy and it connects all of this to the proper context or timing, “

This is a good guideline on Scriptural guidelines and a vision for love and sex in God’s timing when you are both ready.
