Maybe go for erotic novels (or Visual Novels to video games) instead?
Male oriented erotica in book form is rare in US culture, but common in the Japanese light novel / visual novel community.
Books focus on characters thoughts and emotions because that's the medium of words.

Most book-based erotica seems to be aimed at female audiences for some reason, so I think there is a bit of a cultural expectation here.
Still, with the growing popularity of erotic visual novels (and heck, just novels in general) I have to imagine that the male reader base exists out there.

I'm not saying Hunniepop is the best written piece of literature I've seen. But there are words and emotions there, and a mild focus on what the various women want (albeit with the male sex fantasy slants).
Since the majority of the game is in fact, reading mundane situations and figuring out which gifts work best for each girl (ie gameplay mechanic to force the players into reading the story), it forces the player to at least explore the female characters a bit before you get the porno scene.
