I have grown up in a relatively conservative society. I went to all an girl's school until college. Dating was not allowed before college. I had never seen men and women holding hands on the streets. TV started when I was in high school, and there were no kissing scenes. I started watching Hollywood films when I was thirteen. The most romantic films that I remembered were "Breakfast at Tiffany" and "Roman Holidays". Kissing was as far as it went, and it's more romantic than sexual. Besides, those people looked different than we were, I never thought of Chinese people being sexual. Until one day, a friend of mine pointed out this one simple truth to me, and my view of the world has totally changed ever since.
It is in the word. A large portion of Chinese characters are created through images. They are pictographic. The word ancestor is so constructed that the left side means rituals, ceremonies, and the right side is nothing but an image of a penis. What a stroke of genius. It is the origin of everything, isn't it, so to speak. I rest my case. Here is the word, judge it for yourself.
