When youths engage in premarital sex they have some reasons that make them make love before the right time.
They think that the scripture is outdated; they say that when the Scriptures were written, the people during that time got married when they were teens; so they didn't have to struggle with sexual temptation like of this present time.
They too believe that sex produces intimacy.to them when you engage in sex the two partners come together it is like a sign of covenant as it bounds people together. There is one quote that teens believe i strongly in Dr. Patricia Love, the author of The Truth about Love,They donít understand that premarital sex does produce a short-lived chemical cocktail in the brain; there is no guarantee that it will produce long-term emotional closeness or relational satisfaction.that a feeling of intimacy is created by a "chemical cocktail" that is produced in the brain during sex and stays with each person for up to 24 hours after intercourse.
But, Alice Fry ling, in an article titled, Why Wait for Sex? Writes:
Teens imagine that sex determines compatibility, they do say that no one would buy a car without test driving it; so they cannot imagine committing to marriage without taking a "sex test drive.""Genital sex is an expression of intimacy, not the means to intimacy. True intimacy springs from verbal and emotional communion. True intimacy is built on a commitment to honesty, love and freedom. True intimacy is not primarily a sexual encounter. Intimacy, in fact, has almost nothing to do with our sex organs. A prostitute may expose her body, but her relationships are hardly intimate."
But the interesting part of it is that they have hope, even if it is wrong they say God forgives every sin and therefore no sexual sin is beyond God's forgiveness.
I will only recommend that abstinence is good but for those who sin knowing that god is there for them it is too late God helps those people who help themselves and those sins that we do unknowingly are the ones forgiven.
