Why did you take that the child showed scary pictures and scared something else there? At this age, some people already have menstrual periods, so they will have to give some information. Why do you think that a girl must be intimidated to death, so that she doesn’t run away at the first spike of hormones? The normal language is not understood by children. Why, in your opinion, it is normal to say, "Don't go down in the pit - you will fall asleep, you will get sick," but it is not normal to say that from unprotected sex there are pregnancies and / or infections with severe consequences? Of course, if you carefully hide any information about “this” (or even write down what “this” is ugliness), and then take and drop, the reaction will be far from normal. But who’s the parents.
I remember how girls (just 12-13) of our class were gathered and taken to the medical office to receive brochures about menstruation, female anatomy, contraception and the consequences of sex.
