Since women are the primary consumers of erotica, it is a woman's perspective that you need - in addition, of course, to the more visually oriented point of view of men. While men writing erotica would tend to focus more on the sexual act itself, women tend to also need an emotional context. Most women would also want a certain elegance of language and style; crude or dirty language is only sometimes, and not always, desired. As a woman I can give you not only action but also seduction; I can give you not only the fast and furious but also the slow, heady rush of long, sensuous build-ups - not only fucking but fine, red wine. In my stories there would be both sex and romance like the ebb and flow of waves; or like snakes, cool against the skin, coiling, tightening, then loosening, slipping away ... and then to come back once more, perhaps, for a final, wicked bite.
