Dear doctor09, i went through those sites briefly and saw some of them, but not all as it was time consuming and quite alot. Yes, they need to include those material in sex health education, at least the existence of those Ahadith will shut the mouth of those who call sex education Unislamic. But that on its own is not adequate without the modern medical field. These education as somebody rightly said here should be taught to the parents as well, because of the lack of sex education, even the parents go through many difficulties, divorce, domestic violence, etc which directly affects the environment of the household-the kids will be the first to feel the heat. So yes, this type of education is very necessary, although as i mentioned in my very first post in this thread, that the age of pupils and the material taught must be considered along with the sensitivites of the society. Bring some good mullahs to tell people that this education is good for them, this will have maximum effect.
