This topic is really fascinating to me, how we deal with images of bad things. Clearly, murder and assault is fine to reproduce at 100% realism - but even plain consensual sex is forbidden in the US for a wider audience. This reminds me of a classic Swedish movie I watched, I forget its name, it's made in the 70s and contains upskirt panty shots of an actress who is playing a 14-year-old, along with her exploring sexuality with a same-age male peer. I think the actual actress was around 14 years old too. It made me feel real uneasy, maybe because my parents in law were around, but also because I thought "wait, this must be illegal to watch". In the end, the movie was really just a coming-of-age story from a time when we were more relaxed about these things.
