The reality is that talking to a child about sex is, literally, wrong. All that children under the age of 12 need to know is that sex is an adult activity with adult consequences. And nobody is allowed to do it with children.
So, how should we talk to a child as part of sex education?
First of all, you need to work on your own knowledge before educating children: learn to say all the necessary words yourself; study the vocabulary (the correct words for the genitals and all the body processes); study the things a child should know as well as the age at which they are supposed to know them.
Secondly, talk to your child from a very early age about personal boundaries, the fact that “no” means only “no”, and safety rules (e.g., “say no, go away, tell”, “panty rule”).
Thirdly, discuss love, feelings, and emotions with your children; become involved in their lives, kindergarten, and school events, and listen carefully to what they tell you.
Finally, don't act like anything is going on when your children start to mature: talk to them about periods, nocturnal pollution, contraception, the age of consent, and responsibilities under current law.
If you provide children with age-appropriate, reliable information, you will significantly improve your child's safety and well-being.
Here is a little tip on the ages of children:
One last thing. If you no longer have a young child, but a teenager and you realize that you have missed out on something and find it difficult to talk about the topic, we recommend not being shy and contacting a child or adolescent psychologist, firstly for advice, and secondly for working with the child.
