That's really interesting -- I hadn't thought about sex (for some readers) being an integral component of the plot even if it's not specifically to that reader's tastes. The idea that the sex can be a satisfying part of the story without actually needing to be read, just that there's a sex scene in there intrigues me. Out of curiosity, do you think a fade-to-black would be equally satisfying, or does it need to be written out?
