Personally, I don't like short stories much. I'd say I prefer stories about people in loving relationships with realistic relationship dynamics in a believable environment with other characters. In other words, stories that just happen to have intense sex scenes in them. Perhaps you could throw in the occasional superpower, or time travel element in for extra kicks, but it should never take away from the believability of a story or plot. I want to see the development of a character(s), usually the two individuals who make up the couple, from childhood on up even before the characters in question meet in the story. --- Hope this helps add insight for you.
I agree. Luna moths in particular are very arousing to me. The contour of their wings just does something to me, I dunno what it is. Oh, I'm sorry, this was directed at the men. I'll be leaving now.
Frankly the vast majority of erotica that I read these days is short(ish) stories of a somewhat anthropomorphised nature. In particular one writer who (thankfully) is good at both character dynamics, scenarios, etc and elucidating the more primal side of things.
I myself read alot of BDSM porn. I enjoy reading porn because my mind can fill in more what the people in it look like, ect. A well written story can really get you going. Also you can write about alot of fantasy stuff that can not be done in video porn.
