Did I get your attention?
As a writer whose fiction sometimes includes (gasp!) sex, I have a problem with the male genitalia. It’s not that I don’t like the penis – I’m a big fan. It’s because there is just no good way to say its name. Every word, whether scientific or euphemistic, either changes the mood, or kills it altogether. So I tend to write around the problem, by describing the act without naming all the players.
