I don’t know how the authors of gay and/or lesbian romances do it.
Sex scenes are tough no matter what with all those body parts to keep track of. Nobody likes to read about a hero making love to a woman after forgetting to take off his pants or a woman having sex with a guy with three arms. (Unless, of course, he’s an alien with three arms.)
But normally I’ve got a his and a hers. A he and a she. Well, I’m in the middle of editing a scene between two women, and I’ve got hers and hers and a she and a she and even I can’t figure who’s doing what to whom.
I’ve gotta fix that, right? So I substituted their names whereever the pronouns were a little unclear, and now it reads stilted and amateurish.
