Hi, I wasn't into it not long ago, however, once I got my "desire" back, I started seeking out some information and entertainment. Six months ago I would have told you porn doesn't do much for me. Also that in no way means I don't approve--I just didn't see there was anything to it. But fast forward six months to today, and I can see I'm now more interested in "fantasy" which is what many women enjoy about porno.
I have made my way to Brazzers.com which is great. For .25 cents a day, I signed up for a yearly subscription which I access through my iPhone.
Some of the acting is "cheesy", sometimes realistic. Every movie us different, same repetetive plots but different scenes and actors. You may find for your girlfriend this site and the mini movies more acceptable than say "hard core" sites or amateur sites.
Sometimes the plot initially is so long, I find myself sort of frustrated waiting for the sex to begin, now I thought I would never have said that or believed it, but it's true.
Also I find premium cable's The Movie Channel network if channels often have soft porn airing, plus it is available "on demand" nowadays in most areas. Check it out for a month, see if you like it.
I hope this information is helpful for you and your girlfriend.
