People who pay for sex are still not getting their sexual desires met,

How so?

Having talked to and met, literally hundreds of people who do pay for sex - and say that without that service - their sexual desire would not be met, and more importantly - it would detrimental to the rest of their life and relationships, so I would disagree with you there..

My experience of this is not academic, but from years of seeing exactly this, day in day out..
