Austin based author Bill Cotter in an interview with Scott Cheshire Paris Review.
“Make it fun!” This is good theory in general, and, I think, especially important when it comes to writing sex. Sex, the act itself, when viewed without eros, is very silly business, what with all that snuffling and shuddering and pinguid gymnastic theater. It doesn’t look like much fun at all. It is the job of the writer to make it fun on the page, and the only way I know to do this is to subtract sentimentality and add humor. Tease the characters a bit, distract them with jolts and surprises, juxtapose them with highly unerotic fixtures, assign them curious peccadilloes that impede or amplify performance, maybe throw in a shockingly graphic detail or two, to keep the readers on their toes. Make it fun!
