The topic of sex is very awkward for Asian parents, because in traditional culture, people never talked it in the public occasions and they treated it as shame thing. While situation is different in western countries. Children receive sexual education at a very early age. Every teenager should receive right sexual education.
对于亚洲父母来说性是非常尴尬的话题，因为在传统文化中，人们从来不会在公共场合谈论这个话题，他们认为性是羞耻的事情。而在西方国家情况却不一样，孩子们在很小的时候就接受性教育。每个青少年都应该接受正确的性教育。

In China, it is the very classic situation that when the child asks his parents how he comes to the world, then the parents will tell him that he is picked up from the garbage. Parents doing this to avoid sex topic, and they think they are doing the right thing to the child. Actually, they are misleading the young generation to know about the world.
在中国，这是很典型的情况，当孩子问他的父母他是怎么来到这个世界的，父母就会告诉他，他是从垃圾堆里捡回来的。父母这样做是为了避免性的话题，他们认为这对孩子来说是正确的做法。实际上，他们是在误导年轻一代去了解世界。

Look at the western countries, parents will tell something about sex when their kids are in primary school, and school also open relative course to let children know this issue, so as to have right attitude towards it and better protect themselves. 
看看西方国家，父母会在他们孩子们还在上小学的时候就普及一些关于性的知识，学校也会开设相关课程，让孩子对这个话题有所了解，以至于有正确的态度，也能更好的保护自己。

It is in need of receiving proper sexual education for teenagers, so that they can know the world better. 
青少年需要适当接受性教育，以便他们能更好地了解世界。
