Yes, I do believe homosexuality is a fetish. I think you’re absolutely right on that point.
There wouldn’t be so many men addicted to porn, though, if there weren’t so many women willing to entertain them. But, there is so much weird stuff that men (and probably some women) are passing around, too. One young wife (early 20’s) told me that all of the young men today grew up looking at online porn, beginning at a young age, and now every young man she knows is addicted. It’s become a real problem. In the old days, they had to buy a magazine, hide it, etc., and they didn’t have the easy access to the stranger stuff. Now young boys can easily view some pretty disturbing things very easily online.
I wonder if there's any connection between what you observed here and the plethora of ads (apparently aimed at women) for "make $$$$ at home just using your laptop." I can't help but wonder that the laptop must necessarily be equipped with a Webcam.
