Internet pornography, no matter how much it is apart of your life now, wasn't so just a decade ago. The ease of pornographic access is changing society everywhere. Porn, being the biggest industry, is bound to try an accomodate an ever-growing audience and fetish-desires to cope with the changes in the market.
Boob jobs, Periods, Weight Gain/Loss, Ass jobs, Hair, Nails, Facials, High-definition camera, high-quality sound recorder, Lighting, etc etc .. all these things that cost to maintain in real porn, but don't in hentai. Which is why hentai is going to become the market of the masses, and for people who can't do "porn 4 pixels" are going to find it very difficult to satisfy their sexual urges.
