To answer the question, 'what is the reason that abstinence is a good idea for teenagers', I would say there are many reasons why teenagers should abstain from sex. The principal purpose of sex is procreation, that is giving birth to babies, all the other benefits of sex are secondary. Thus, sex is meant for married couples and not teenagers. Indulging in pre-marital sex has many side effects both physically and spiritually. The physical side effects include: risk of getting infected with serious diseases which may lead to untimely death, risk of not been able to give birth again when married due to removal of womb as result of multiple abortions, negative psychological experience as a result of consequences of premarital sex, devaluation of future intimacy with one's future partner, aggravation of sexual desire making one insatiable, it produces unwanted babies who are treated badly and who become miscreants in the society, etc. The list is endless, above all, it is against God's law. Abstinence does not have any side effect.
