I am an old pervert, and I have been on the internet since before it was the internet. What originally drove my interest in the internet and computers was a search for porn. I am not stranger to the deviant side of the internet.
And yet somehow, the existence of this particular form of porn has escaped me. I know there are many and varied forms of porn that I have never seen, but until today I thought that they were all niche things, and not something that there is enough to influence the sexual development of someone...
You have taught me something new today.
