Well, I haven't looked this up (Puritan Sexy Love), but my vision of porn was to go anti-XTREME and make tame, banal, boring stuff (and, of course, this would be it's selling point).
This probably exists already. I just don't know much about what the porn industry offers.
I'm afraid to start looking up the crazy Puritan stuff linked above. Ha! I'll be getting pop-up ads for burlap condoms.
