So if I we're to be a famous novelist someday and you happen to read one of my novels with embarrassing depictions of sex or other habits, you have to trust that it's 100% true.
Hey, better that than having a depiction of sex written by somebody who has no idea how it really goes, eh?
(Apparently this really common romance novel cliche, where a heterosexual pair couple up one night and then just sort of stay joined at the genitals until dawn because they're so in lurve and it's romantic...does not work in real life. At all.)
As a fiction writer, I consider all life experience research for a novel. Sometimes I feel weird about it, so I do try to tone it down or mix it up a bit, but I think you're quite brave to keep it straight...and, once I gain more confidence, I'm sure that I'll writing out 100% true-to-life and true-to-
my-life stuff, too.
