hello blushingm,
feeling a bit bad that I may have been too strident yesterday.
To answer your question simply, yes of course we still fancy our partners even if we look at porn. When we look at porn, we are not fancying (in the true sense) the people in the scenes, we are just creating a bit of fantasy in our heads. And everyone needs a bit of fantasy, IMHO. i.e. no single person can provide for every single one of our needs, sexual or otherwise. Now, in the worst case, people go off and have affairs, something I have never ever done. So it is not too bad a scenario if it is limited to looking at a bit of porn in the privacy of one's own home.
In reality, whatever the rights and wrongs, people have looked at porn since time imemorial and stopping your DH from doing so is, I fear, counter productive.
Perhaps you could even look at some porn together as a stimulus for your own love life?
Porn is not a panacea but at the same time it is not the devil incarnate either.
I do hope that helps and that you can both find solutions which help you both feel comfortable.
Sorry not at my most articulate this morning, at work and having to write quickly!
