Sex without plot turns rapidly in boring anatomical description.

Plot without sex, well without BDSM as we are here, is just another story at the bookstore and does not fit the expectations of this site's readers.

I'm like a young child: When given the choice, I want both. Dessert AND Cheese; Applepie AND Jelly... Sex serving the plot, and plot serving sex.
And never forget, the most enjoyable part is the foreplay!

I wonder where you put 'Expression of Feelings and mood': in sex or plot part ?
