@SharingtheLove,
An why oh way should someone watching porn or not watching porn be of such a great concern to you or for that matter women as a class?
Do not see why that subject is something that you would need to be more up-front about then a million on one other hobbies or interests with a woman in a man life.
It would be like expecting a woman to have a need to be upfront about enjoying reading a book of women romance fiction being hold in one hand while using a vibrator with the other hand.
Neither the video porn or the book/vibrator should have any great impact on a man/woman relationship sexual or otherwise.
