Saluki, huny,
I am thinking this is not so big a problem...but I could be wrong. As others have said here, men seem to like porn, though I agree with you that it is degrading to women.
Is he faithful to you...a loving and caring partner? If so, this may just be his hormones working overtime. If you feel, though, that is an ongoing problem, and that he is obsessed with this kind of imagery, then maybe you need to rethink your relationship.
Sorry, I can't be more help in this.
Many years ago, I was best friends with a woman who was a talented musician and artist. He husband was gifted musician as well, and who was even featured in PEOPLE Magazine for his talent as a builder of guitars for the "stars" of music. She told me that he liked to view porn movies regularly, before having sex with her. She divorced him and moved on. It saddened me to hear this, as I loved and admired them both.
I don't know what to tell you about your current situation other than to say "be watchful."
Love
Patty
