Why sex education is not being emphasized in Malaysia?

Just like my group members said...actually our country had did something to implement sex education, but it is not enough...the government should put more effort on it but before that, they should know the reason why sex education is not being emphasized in Malaysia first...for me, one of the reason is because parents and the educators themselves lack of the knowledge on sex and so they are not able to pass on the information or knowledge to their children and students. Moreover, some of them still have the conservative thinking that they feel shy to talk on this topic-SEX. For an example, last time in school, during my biology class, my teacher just very fast went through the topic that about sex without explaining it in details. This will let the students wondering what is actually sex about and so they will just follow what the actors did in the movie. Indirectly, this will cause the social illness become more and more serious since they don't have the true information on sex.
