With regard to statutory rape laws, there are a few "tiers" built into the law; i.e., Age of consent may be 16 but if a child under 16 has sex with someone within 2, 3 (e.g. Miss) or 4 (e.g. Pa) years of their age, it is not stat rape. Then many states have laws that make having sex with someone under a certain age (12 or 13 in most jurisdictions) it is illegal regardless of the partner's age.

Child porn laws are ambiguous or silent regarding age difference of recipients.

The linked article confirms something I have observed in my limited dealings with the issue in my own practice: More often than not teen girls are the ones initiating the nude pics as opposed to the boys. And while boys may be horn dogs, teen girls are really getting more sexually agressive often being the ones initiating sex.
