There are two banquet halls for men and women, and I can't remember the video I watched on the screen. I vaguely know some pictures of menstruation and uterus. Did you watch the' propaganda film' in junior high school? My mother told me not to fuck around outside. ╮ (╳ ╳) ╭ Teaching biology in junior high school. At that time, the biology teacher didn't teach a class. Probably just look at the picture and tell us to guard against people, and then make a long speech. Actually, I don't really understand it. It probably means knowing. "Protect yourself, boys and girls alike." I remember the biology teacher also said contraception. At that time, several students chased the teacher and asked what brand was the best. The teacher also answered very carefully, and then someone remembered. But there are also some people who play the same. My parents just told me not to run around with others. No sex education. At best, just ask. I hope it helps you, and I wish you a happy life ~
