I don't have any kids, but I sometimes think about whether I'd try to shelter a pre-teen from things like internet porn. I doubt in 15+ hours when I have a pre-teen I will be able to. I would definitely have "the talk" and discuss how most pornography is not realistic of most people's sex lives (and that it often shows degrading acts one of the actors doesn't appear to consent to).

But maybe it's worth considering providing them with "safe" porn - stuff that shows non-scripted, non-degrading, consensual sex acts. The idea is to give them access to stuff that doesn't objectify women so explicitly or role play things like non-consensual or coerced sex, which seems very prevalent. I can't keep them from whatever niche porn they want to see on their eyeball implant iPhones in 15 years, but maybe I can help provide them context to understand that what they're seeing is unrealistic and isn't how women should be treated without their consent.
