how many people have ever payed for porn

since i first got my hands on hardcore porn at the age of 11 i've been in a constant cycle of building up a collection then being so apalled by the shear volume of it all that i give it away. a few weeks pass using my imagination then it starts again. i currently have over eighty DVD's, i haven't got a clue where they even came from. i've never once bought any. they all came from friends, and i know they didn't buy them either. where does it all come from? everyone i know always just gets them off someone who got them off someone. and now with the internet its even easier to find free porn. so i just want to know how many of you have ever paid for porn?
