Ok, I'll play along, even though the original question quickly devolved into the catch-all "so what gets you off, ladies?!!"
As has been discussed before, most porn is aimed at a male audience (straight or gay). Back in the day when the first stag films were rolling out of Ye Olde Pornoe Shoppe it was thought women would be a) offended and b) if not that, then for sure never aroused (the old "men respond to visual stimulation, women ehhhhhh not so much" sweeping generalization). Soooooo, since most commercial porn is aimed at guys, no, I don't find much of it entertaining. I don't like watching people (male or female) who perform like wind-up dolls. Forget the dialogue (and the music - eek), can't the director at least suggest that the performers "act" like they're actually enjoying the sex they're having on that hot soundstage in front of various crew members and those 3 fat Teamsters? And as soon as I see a woman on her back on a waterbed wearing thigh-high leopard-skin boots with 6-inch lucite heels, I'm sorry, any possibility of arousal is lost in peals of laughter. That's just wrong on so many levels. Having said all that, I would still gladly worship at the altar of Peter North.
I have heard there are some alternative porn production companies exploring various niches and fetishes, but I'm not really kinky enough to know much about that. I do think the current DIY porn movement is very interesting... and I really only learned of that on here (thank you, LPSG)! Seeing real people/couples going at it is a lot more stimulating to me than watching 2 bags of silicone bounce on top of some overly-waxed metrosexual with a bad shag haircut.
I also will give a big shout-out to Anne "bless her born-again little heart" Rice for her amazing Sleeping Beauty erotica, which took that traditional fairy tale and turned it on its head... and then gagged and bound and spanked and f*cked the hell out of it. I'll debase myself to admit that that trilogy impacted my sexuality (and so, my life) in a MAJOR way. I actually had an orgasm while reading one particularly steamy chapter - and I wasn't touching myself. Verily, that was an unusual reading experience for me, and it was only the beginning. :wink:
