As a woman I found that how my man viewed porn made all the difference. My first husband used to look at porn by himself and substituted it for sex with me. Not surprising I was miffed

But my last BF showed me the porn and together we looked at it and made comments, like s/he is hot, or wow how do they do that and stuff like that. It was fun when it was a shared activity and led to more fun in the bedroom.

I don't think you can make a blanket statement about whether porn is good or bad. It depends on the couple and how the porn is viewed and how the couple communicates about it.

My two cents...
