"Say: Are they equal those who know, and those who do not know?" (Quran 39:9).
"Blessed are the women of the Helpers. Their modesty did not stand in the way of their seeking knowledge about their religion" (Saying of the Prophet - Bukhari and Muslim).
Although the Quran has placed so much emphasis on acquiring knowledge, and in the days of Prophet Muhammad Muslim men and women were never too shy to ask him questions including those related to private affairs such as sexual life, for Muslim parents of today, sex is a dirty word. They feel uncomfortable in discussing sex education with their children, but do not mind the same being taught at their children's school by secular or non-Muslim teachers (of even the opposite sex), by their peers of either sex, and by the media and television. An average child is exposed to 9000 sexual scenes per year.
These parents should know that sex is not always a dirty word. It is an important aspect of our life. God Who cares for all the aspects of our life, and not just the way of worshiping Him, discusses reproduction, creation, family life, menstruation and even ejaculation in the Quran. Prophet Muhammad , who was sent to us as an example, discussed many aspects of sexual life including sexual positions with his Companions.
The main reason Muslim parents do not or cannot discuss sex education with their children is because of the their cultural upbringing, not their religious training. They are often brought up in a state of ignorance in regard to sex issues. As a result, they may not be comfortable with their own sexuality or its expression. They leave Islamic education to Islamic Sunday schools and sex education to American public schools and the media.
What is sex education and who should give it?
Is sex education about knowing the anatomy and physiology of the human body or about the act of sex or about reproduction and family life or about prevention of sexually transmitted diseases and unwanted pregnancy? Is giving sex ed equivalent to permission in engaging in sex? One sex educator at my son's school told the parents, "I am not planning to tell your children whether or not they should engage in sex or how to do it but in case they decide to do it, they should know how to prevent sexually transmitted diseases (STD), venereal diseases (VD), acquired immune deficiency syndrome (AIDS) and pregnancy."
The problem with this is that at the present time sex ed as taught in the public schools is incomplete. It does not cover morality associated with sex, sexual dysfunctions and deviations and the institution of marriage.
One of the basic questions is, "Do children need sex education?" Do you teach a baby duck how to swim or just put it in the water and let it swim? After all, for thousands of years men and women have been having sex without any formal education. In many traditional civilizations, sex education starts after marriage and with trial and error. Some couples learn it faster than others and do it better than others due to difference in sexual perception and expression of one partner. In my opinion having a dozen children is not necessarily proof of their love. An appropriate and healthy sex education is crucial to the fulfillment of a happy marriage.
