I was from the first generation to experience this, by being raised on the internet in the 90s. But I guess I had to just kinda figure it out on my own. I think it's important to have external education about this from other sources, but I'm not aware of any good sources on this.
A lot of religious institutions tend to rely on shame and taboo to persuade children/teens from watching porn. But I don't think that's effective either, shame and suppression can cause other issues.
I think even outside of porn it's important to understand this about all forms of media, that most of it is thin and largely fake. Media addiction and letting it affect your perception of reality is a general problem, especially today in the on-demand era.
If anyone else has good recommendations, please chime in.
