Pornography: “normal” and “healthy", or harmful addiction?

While Russia and Ukraine gets all the views, the real reason I started posting videos here was more about current life in the West. There are many worrying trends. One that is not much discussed is the constant sexualization of children and teenagers, and the normalization of pornography. The first part here shows recent animation clips directed to teens and pre-teens, promoting porn and masturbation as “healthy” and “normal”. The second part is a talk by Gary Wilson talking about its bad effects, which is interesting and can be seen in its entirety here: https://www.youtube.com/watch?v=wSF82AwSDiU The last clip is from another animation which summarizes a few of Wilson’s points. Personally I haven’t watched porn in years, and I think no one should, I doubt it is healthy for anyone’s mental health, and it’s obviously a form of addiction.
P. S. How come in the first clip the "brother" and the "sister" are of different colours/races? I guess this is a push for multiculturalism, another trend in the West, but here it doesn't even make sense.
