Does a man’s perception of women change after pornography use? Yes if the porn use was habitual

Will this affect how his wife is treated during the marital embrace? Possibly, but it's more likely to cause him performance anxiety

 Does his use of pornography change his perception of women in general, even traditional Catholic women? Yes if the porn use was habitual

Does he hold resentment towards women because of having had purity problems due to the pornography industry? I don't see why. If he's Catholic he's probably more resentful towards himself to have engaged in an addiction that warped his view of women and the marital embrace

 Is it better that a man not be a virgin (slip up once) than to have been a habitual user of pornography? It's better for him not be a virgin than to have been a compulsive porn consumer.
