I once saw a PPT for adolescent education on the Internet. You can download it and watch it with her. So don't talk so much. However, if you are a mother, basic adolescent hygiene seems to tell her better. For example, menstrual hygiene (let her look at sanitary napkins and other things, the child must be curious, you don't let her have direct contact, she has plenty of methods), how to get pregnant, how to protect herself (to save her life or be chaste), and your daughter is happy, at least you will make these efforts.
