Ko Young-geun: Sexual knowledge that enables a joyful longevity

This is the 100-year-old age of longevity. Many lived to be over 100 years old. If you enjoy life by the age of 100, you will have to be able to live sexually even in your 90s. Because the desire for sex is to have people die, so if you live to 100 years of age, it is a happy life to live with those desires in your 90s. People are said to have sexual desires until death, but even in their 90s, there are not many people with sexual desires, and even fewer people have sexual abilities. Most people lose their sexual ability in their 90s, so they lose their sex desire. And I've had a very unusual sexual life experience in my 80s and 90s. Of the text -.
