I always smile when I see remarks like this. It reminds me of heavy handed moral-types who would come out from under their rocks about once every two years or so with some kind of report on porno videos.
"Every hour of porno we evaluated had six acts of oral sex, three acts of anal penetration, one threesome scene, etc etc"
I was always impressed that such devout types, ostensibly disgusted by it all, would take their analysis of it so thoroughly! A shame that they forced themselves to sit through 100s of hours of that stuff, huh? :-)
