The 20 "doors" of the "post-90 s" are not blocked. In the past two years, violent pornographic incidents among teenagers have emerged one after another, and many "doors" have been created on the Internet, such as "making love" in the classroom of Handan University, "touching milk door" in Cixi Vocational High School, "taking off pants" in Shunyi, Beijing, "touching birds" in Hunan kindergarten teachers, "airplane doors" in libraries and "airplane doors" in Hunan schools.

The "post-90 s" incident has three characteristics: younger sexual behavior, low-level imitation and spoof. I don't think this is a disaster. Of course, there must be a bottom line: no pregnancy, no illness, no harm to the interests of others. In fact, every generation has a rebellious period, but it will converge later. Just like before, we were worried that the post-80s generation was too open-minded, but now they have become orthodox, calling them "post-90s generation" and "idiots" on the Internet. Perhaps, when "post-00" appears on the stage, "post-90" becomes orthodoxy. Teenagers' sexual problems can't be stopped, but the key is to clear them up. We can't panic, but we can't let it go. Sex culture should also advocate the main theme and give guidance. Sex education cannot be "threatening" education. Tell him that sex is beautiful, but you must be responsible.
