I doubt if anyone knows, or even cares, but Loooong ago, before the adult film industry adopted it as a "bumper sticker," I posted my thoughts on Adult DVD Talk, perhaps the biggest industry oriented forum, in which I concluded---"Thus,to require prophylactics on male performers, tested more often than lab rats at UCLA, was just plain, "stupid," and, when "forced" upon f any adult film scene, they'll always be 'ConDUMBS" to me.
I have no doubt, then, that someone associated with adult films, read my post, adopted it as his/her own, and "ran with it."
But thats ok with me, as long as the most STUPID/DUMB proposal ever made by the LA County Commission is soundly defeated, and that I will have the satisfaction in knowing, MY wording may have played some small part in its demise!
