Definitely not. Minors, especially 12 - year - olds, are in a vulnerable stage of development. Sharing sexual stories about them violates basic moral principles. It can also cause harm to the child if such stories are spread, as it may expose them to unwanted attention or stigma.
It is highly inappropriate. Our society has a responsibility to safeguard the innocence of children. A 12 - year - old is not ready for any form of sexual exposure or discussion. Moreover, in many places, any form of sexual exploitation or inappropriate talk about minors is against the law. We should focus on positive aspects of a child's life like education, growth, and healthy relationships.
