Talk to her. Ask her what about porn bother's her the most. Ask her if she would be willing to watch one movie with you. If she says yes...buy her fav bottle of wine...or whatever, get a "mellow" porn ..... hint...not one with some chick getting it up the A$$. Try to have one with some "romance" kinda crap in it. And god don't let it be Ron Jeremy!!!! A good looking man is a plus! Also, I would be hesitant to try and initiate sex that first time. She MAY think the only reason you want it is because of the porn.
We are emotional creatures. Where you can sit and watch porn and analyze technique....we look at it and think...I don't do enough for him. I'm not pretty enough, or my body isn't as great as it could be soooooo for him to get "off" he has to watch porn.
Personally........porn doesn't bother me. Hell, I bought the Snoop dog video for my ex...watched it with him and well..........the rest is a little X for this board 
If she can't get past the discomfort with porn, you need to decide what is more important....her or the porn!
Good luck

Women over 30 are dignified. They seldom have a screaming match with you at the opera or in the middle of an expensive restaurant. Of course, if you deserve it, they won't hesitate to shoot you, if they think they can get away with it.
For all those men who say, "Why buy the cow when you can get the milk for free". Here's an update for you. Nowadays 80% of women are against marriage, why? Because women realize it's not worth buying an entire Pig, just to get a little sausage.
What the mind can conceive....the body will achieve!
