What is "sexposition"

In visual media such as television and film, sexposition is the technique of providing exposition against a backdrop of sex or nudity. The Financial Times defined sexposition as "keeping viewers hooked by combining complex plot exposition with explicit sexual goings-on". Its purpose, according to James Poniewozik, is to divert the audience and give characters something to do while exposition is being delivered, which is what distinguishes sexposition from merely gratuitous titillation.
