The stage of adolescence marks the end of childhood and the beginning of what will be the adult life of a person, manifesting a physical and emotional growth. A teenager is ready to start experiencing sex and with it the possibility of procreation.

The changes that the adolescent experiences related to his sexuality are:

1. Interest and attraction to other people

2. Interest in highlighting their physical attractiveness

3. The psychological function of sexual impulses begins

4. The need to feel pleasure appears

In the sex education part, parents bear the main responsibility for informing their children about the benefits of this new stage, as well as the protection of their health and consequences that may result in endangering the health of the adolescent.
