Can't say I'm a fan of the Hentai. If I didn't have pics/vids of real people available then maybe, but it's not like there's a shortage of these on the internet. I guess it's that I like the idea of authenticity more than that of sex or figures in the abstract. I like porn that shows recognisable human emotions and moods, like desire, playfulness, pleasure etc. I've always thought of Hentai as being a more extreme version of artificially "enhanced" pornstars, with more scope for idealism (for example, the ratio of waist width to breast size in the above pic). And I don't like artificial enhancements because they somehow make everything look inauthentic and, well, dull.
