Not really virtual porn, but it's a similar concept. It's the S.1 episode called The Entire History of You. Check it out!

In the meantime, I definitely see where you're coming from with the concern. And @craig-grant is right. Porn was a major innovator in terms of most tech development, from film and audio quality, to medium platforms. But on the bright side, people who aren't interested it will be the ones most likely to pass on genetic material. Humans can handle that level of tech, I'm sure.

Thanks for the post! Great thought!
