Unfortunately, this isn't just a question of interpretation. Legally, there's no differentiation between those two categories. One is more ethically problematic than the other for sure, but you're just as screwed having either on your computer. You can see this most clearly in sexting cases against high school students. You can still get on the sex offender registry for sending a picture of yourself to your boyfriend or girlfriend and there's tons of stuff like that on /b/.
