Um, wouldn't the perpetrator be the person they sent the nude pics to? Common consensus is that it's somehow grooming to have any type of romantic relationship with someone who's under the age of majority, even if you're also under the age of majority. So even if you're not the one who sent the nude photos, you'd still be to blame for creating an environment that enabled them. At least that's the impression I've gotten from my own experiences with this bullshit.
