I do not believe all men watch porn.
However I wonder why they dont with it now being the "norm"?
Was there never any interest in the first place? Has it lost its shine? Is it a for feminist reasons?
Or is it more of a case of resisting temptation? As in they do want to watch but guilt and/or morals stop them? Fear of being caught?
We live in a time when we are constantly fed the message all men watch porn so nobody ever discusses those that don't watch it.
