As for the effectiveness of porn, I don't want to get into a debate; you either like or you don't I guess. I'd be lying if I said I wasn't ever put in the mood by porn, but on the other hand it is pretty easy for me to see the humor and ridiculousness of it too.
Different strokes for, uh... whatever.
