I just really don't think this solves the problem that she is suggesting exists.
Either you're a teenager who watches pornography and wouldn't care for whatever sanitized version that would exist for this (I believe in teaching more about e.g. consent, but that doesn't mean when I'm watching a video that I need to see them acquire it) or teenagers who don't watch pornography would watch more, which isn't bad but I don't see how it's good either.
The idea of pornography motivated as a teaching tool for people to have sex seems like a weird place to try to instill these values.
