What do women think of a married man who looks at porn?

I am curious how women respond to a man who looks at porn though he is married. I do not necessarily mean your own husband, but men in general. When I was young if a guy looked at porn both men and women laughed at him (though of course plenty looked anyway). But now it seems like so many men do look at it and I am wondering if attitudes have changed. For the record, I try not to look at it myself for my wife
