I draw on the usual comparison with gays. It is and has been considered 'unnatural' to have sex with a member of the same sex. It does not produce children and does not do anything for the human race.

The same is true of adult-child sex. It is unnatural because it produces no children. Hmmm but what of sex with a 13 yr old? If the person is post-pubescent then it must be a natural state and let me tell you I have observed 13 yr-olds who are all over each other. Don't let anyone tell you it's not natural. Of pre-pre-pubescents?

The female form, including pre-pubescents, is attractive to all men (except a few gay men). I'm not sure about female attractions so much Violet.
