In life, there is a difference in perception, attitudes, and behaviour of spouses is reasonable. No exception in the Affairs of sex. Like the difference in household affairs of the other, if managed properly, the difference in sex matters thus could be a liaison for mutual understanding. But if not managed correctly, the difference can be a source of discord.
In fact, the relationship of husband and wife is the unification of the various differences. Physical or psychic, men are much different than women. In General, men tend to be active while the women tend to be passive. Male wants sex, female desires the taste of blissful.

Sex is taboo in our home; we seldom talk about it. My mother has never explained to me the "facts of life" and about the female body and except for necessary things (like buying my first bra) she refused to talk about "those things". She says that sex is a dangerous, primitive and animalistic drive and a woman should keep her sexual impulses inside; that a woman should watch out for and control how she expresses herself; that a woman should be modest. I am a curious person so I had to find everything out by myself because I can't even ask my married sister who holds the same attitudes as my mother.
I understand, the majority of older people, it is still considered a taboo and inappropriate to implement sex education to their children. But thus it should need to be changed.

In my opinion.
sex education on children is a task at once the responsibility of the parents, while the only other institution or as a supporting unit only.

But, in providing sex education on children, parents need to pay attention to the sense of security and comfort the child, that parent should have no need to be shy in explaining something to a child or when answering a question that leveled fruit hearts them.
"Sex education Material needs to be delivered in the warm atmosphere of the family, provide the correct information and scientific, communicates with simple language so that children understand. In addition, parents should also be quiet, not surprised or shy when describing something, give an explanation of according the age children and limiting answers or explanations only on the question of children.

**IT IS IMPORTANT **to be aware of parents in parenting and educating children is to give confidence in children that he loved for what it is so that children feel safe and trust in parents.

Parents also should show an open attitude, ready to discuss with children, are able to communicate clearly.
"In sexual development, parents need not worry excessively, but need to know the things to do and sensitive to change.
