Christian BoyLove Forum #65012
categorises the degree of seriousness of CP images from one to five:
Level one - Images of erotic posing, with no sexual activity,
Level two - non -penetrative sexual activities between children, or solo masturbation by a child;
Level three - non-penetrative sexual activity between adults and children;
Level four - penetrative sexual activity involving a child or children, or both children and adults;
Level five - sadism or involving the penetration of, or by, an animal.
So your defence would have to be that there is no 'erotic posing' - which is an incredibly subjective test. So I suspect you'd do well to find a bonfire...
