Exact terms then.

Having a sexual relationship with a child is against the law in every country in the world.

So, to get to my point... Because having a sexual relationship with a child is against the law in every country in the world, the child is emotionally scarred after having such a loving encounter, then is told that this is not acceptable is harmful to the child. And the adult too for that matter.

Simpler terms... The child is introduced to sex. Enjoys sex. Then is told sex is wrong!

Sounds like a recipe for loneliness.
