A Complete History of My Sexual Failures is a 2008 British documentary film directed by Chris Waitt who also starred as the main character and composed some of the music.

Filmmaker Chris Waitt sets out on a quest to find out why his romantic relationships have ended in complete failure.

The Daily Telegraph's Mike McCahill, doubting the veracity of Waitt's story, concluded that "It's a display of gross bad faith both as documentarist and lover, and its subject probably deserves never to get laid again.

"[3] On the other hand, Toby Young writing in The Independent, despite thinking that "If Waitt was an employee of the BBC he'd be dragged before a series of committees before being tossed into the street" nonetheless concluded that "this doesn't matter at all" as the film was "so funny I thought I would pass out".
