My knowledge of sexuality education was learned in my college dormitory. At that time, I was 19 years old and was shocked when my roommate talked about these topics. Looking back now, Chinese sex education is extremely failed and quite absurd. I was 19 years old and still didn't know how children are born.

And back then, I liked to browse forums and the like, and I saw many posts saying that you must find a virgin or something. I was convinced at the time that sex is a dirty thing. As soon as it happens, it becomes dirty.
This is an extremely failed sex education and a distorted social value system.
As a result, today we see that the Chinese-language community is sexually repressed, and many people who punch each other in the face are groups driven to madness.
