Photos are lame, especially if they're just naked people. Ooh, big deal, they're naked. I know plenty of men go for that but as a woman I just do not get it, be it a man or a woman that simply took their clothes off.
No, if I look at porn (which isn't too often) it has to be video, there has to be sound, and there has to be action. And I'm not talking about making out.
I've done the reading porn thing in the past but I can't say I'm a big fan. I find myself skipping the story parts and just getting to the action. I do like fantasy but if it takes too long it's just not worth it.
Keeping a basic concept in my head can help me get there but convoluted intrigue is not what I go for when I reach for porn.
