It is an.....interesting thing.
I mean - on the basest level - porn is simultaneously pure masculine driven escapism, much like, say, brothels and action movies, while being a gross example of human degradation and exploitation, much like.....well.....brothels and action movies.
Porn is the lowest common denominator of entertainment, and despite the various opinions about the destruction of the feminine image, the death of basic human decency etc. it has been, and always will be, a form of entertainment designed to make money.
I mean...the media marketing adage is basically 'sex sells', and so porn will always sell.
Personally - I'm not a great fan of porn.
Perhaps I should do some more research into the subject...see if my opinion changes.
