Agreed!

This is true

It may be that the 

• The availability of porn is unnatural 

but once it is available, the compulsion to view it is natural because the human psyche is not designed with effective resistance to it. The genetic brake or clutch which the animals are endowed with, where they are not generally aroused by the nudity of their own kind, seems to be lacking in humans. That may be the issue.

Genetic brake is lacking.

Also seeing naked genitals is not the only porn. There are 2 types of porn, soft porn and hard porn.

Soft porn is nothing naked, just superficial. Hard porn is where naked reproductive organs are displayed in an animal fashion. 

These days, this soft porn is spread everywhere, in movies, youtube and ads. With cumulative exposure to soft porn intentionally or unintentionally, one will be curious or gravitate to see hard porn. If addicted to hard porn, soft porn can be a gear down but eventually, that will add pressure to gear up to hard porn. So, it is an endless loop. 

Internet, globalization, and video technology have opened the doors to the

1. the variety of available
   1. Serbian man would have never seen an Indian-bodied person in his vicinity and vice versa
   2. Now, all the doors are opened and who knows which variety or flavor of the physical body one would be attracted
   3. The wonders of the sexual world are multiplying and overwhelming. There will never a saturation in this domain. 
   4. Back in the day, for an adult movie, the actresses would be limited or restricted to one region, now they can import or even do software tricks like a deep fake to morph faces to delight the audiences
2. Also, in every movie, tittok, youtube, vlog, or ad, sexual energy has gradually increased to exponential levels now. 
   1. In youtube, I was watching a 1980s toothpaste ad, it had no sexuality and there was no need for it.
   2. Since the 2000s, voluptuous actresses with glamorous clothes and selling toothpaste showing their teeth.
   3. They are not only pushing the "Red Colored" toothpaste product into psychic senses of the people but also borrowing the additional sexual energy of the actor and shoved into the audience's psyche. Now, some percentage of the population is just going to buy the product due to the pressure of that sexual energy flavor.
   4. Now, if I have watched 4-5 such ads with such underlying sexual energy between a movie, it adds up eventually to hard porn.
3. The human body is also changing both biologically and psychically, generation after generation
   1. External sexual pressures and frustration are increasing generation after generation and the body's internal psychic and biological resistance is also weakening
   2. If similar nearby kundalini procures certain sexual tastes and enjoys them, the other kundalinis psychically sense them and crave the same, this creates a mass craving for certain sexual favors, which we call a viral sensation and the market for such energy shoots up and they proliferate until next sensation comes!

These challenges and the velocity of change were not there in the 1970s-80s, from the 90s it has increased. So, it may be fair to say the availability of soft porn is increasing and hard porn is just looking behind the doors watching for its turn.

Once 3D technology comes, I will run away and hide. I feel bad for the coming generations because the first reference and flavor the next generation of teenagers gonna taste is going to be the strongest and etched hard in their psyche. They may not even come to have sexual relationships with actual humans when they feel it is not as addictive or potent as they see in digital media and choose to just live with the gadgets, which is already happening now.
