>I'm not really comfortable with the "perverted" label. But obviously any act on another without consent is wrong, and kids below a certain age can't give consent.

There's also the whole array of murky situations where consent is squeezed out of an otherwise unwilling participant by means of economy. I'd count that as just another form of violence.
