How to explain sexual abuse to children?

My son asked me to explain the words "sexual assault". I told him that they are adults who play with the little girls and little boys, but I wonder how to teach a child not to be misled.

It is not enough, in order to protect a child, to explain to him that it is necessary to say "no", because its capacity to do so depends on what it is. First of all, he must be perfectly informed about sexuality - it is often out of curiosity that children follow the pedophiles - and this in a serious way.

It is necessary to teach him the anatomy of men and women, and to explain to him what sexual intercourse consists in using the "real words": penis, testicles, vagina, & c. In this respect, your explanation, "the zizi of girls and boys", questions me. She is very "baby" and, above all, it does not make it possible to understand the difference of the sexes since the same word names both sexes.

Secondly, the child must be informed of the prohibition of incest and of sexuality between adults and children. By pointing out that some adults pretend to ignore this prohibition and should be protected.
But the child must also be aware that his body belongs to him and that he has value. This implies that he has mastery of it, that is to say that he is as soon as possible capable of coping alone in everyday life.

Finally, the child's body must be "respected", that is to say that adults do not provoke erotic emotions (bathing or sleeping with him, washing it then That it knows how to do it, etc.). Otherwise, the child tends to seek out these emotions and this diminishes his ability to resist the suggestions of transgressing adults.
