為何人的性欲會這麼強烈？

It is simple as Human beings is one of the animal in the world and animal have to maintain the continuity of their spieces so that reproduction is necessary.
Of course, some people will have a much stronger desire for the sex but it should be common for all of us.
If the sex is safe, nothing is wrong with that!

這不論是動物或人類都好常見,生物必須通過性行為去生育,有D係天生的.當然,有些人的性慾較強但是這是正常的,如果性是安全的話,咁就根本無罪/無錯
