Why does any guy watch porn?
Seriously though, without getting into the beginnings of the internet, I watched porn for the same reason every other guy watched porn. Though, the internet brought forth a little more curiosity in me and I eventually found myself searching out the sick things people do to each other to get off. It changed me for a time. I would like to tell you that i've come away quite a bit more cynical towards humanity, but in reality, i've come full circle. I was blissfully unaware before, and i'm blissfully uncaring now. Back in the early days of porn, watching a golden shower video was a good laugh as you and your buddies tried not to puke. I had more than my share of jeering as I saved images of women getting bound with elaborate knots because i've always been a fan of rope work (as in knots used in construction, not in sex).
Why I watch porn today is because I have fantasies just like every other person. To see them on screen is a plus.
