Porno shoots stop for a range of reasons: condom breakage, desperate requests for lube, hair and makeup emergencies (actor Peter North is notoriously protective of his coif), bodily functions gone awry as a result of relentless probing. But no on-set issue could possibly be more banal than a lighting adjustment. Imagine you were at home — or anywhere, really — enjoying an encounter with your wife or girlfriend when a director declares that your room is too dark. A technician would then materialize to adjust the lighting while you sat down, gripping your penis to ensure your erection doesn’t fade, and waited for the sex to resume. Such is a normal day on the set of a porno movie.
