I think the key word is informed consent.

I think the key word is informed consent.

"informed" consent is ONLY for medical opperations NOT for sex.

I think consent in this case is based on the ability of people to understand complex concepts and consequences. Children cannot do this, thus they cannot give consent. Thus it is a violation of rights.

Same as anyone of diminished capacity. The insane, the senile or otherwise demented, the unconscious, etc.
