Only seen a few celebrity tapes husbands choice: Paris H.- Kim K.- Pamela A. Decided famous aren't good at sex. Did watch one movie with a guy advertised as 14". I think not. He did have a nice sized dick, but did little to please the women he was with. I would call it degrading to the women.
As a young teen, I would have appreciated porn that was actually educational and taught good sexual techniques, and positions among other things. But I think I'm in the minority as a male expecting this from porn.
I don't think you're in the minority at all. If anything I think you're more likely to be in the majority. The problem is that the porn industry tends to have a totally warped image of what sort of thing is really preferred. As for being educational, there is one video that I've come across that takes an entirely medical view, even using internal cameras. It's been online for quite a while, but is as genuinely educational now as it ever was: http://www.xvideos.com/video32327/internal_vagina_sex
I know the title of that documentary from which that clip is taken from, unfortunately I think it's banned in the USA, because they're all prudish. If anybody here can help find that series it aired in the UK, and I'm really trying to get my hands on it. It's called "A Girl's Guide to 21st Century Sex" --- What do you mean by boring romantic erotica, like cookie cutter erotica in terms of story development and structure? I've read some really good stuff that had a lot of story to it, it wasn't just about the sex scene if that's the kinda boring you are referring to.
I like to watch it every other day or week and I can watch it for either a few minutes or a few hours. I like to watch almost all kinds of porn, but I find myself partial to science fiction, fantasy, and hentai sort of stuff.
