A Complete History of My Sexual Failures is not only a hilarious and touching portrait of a man whose psyche is arrested in an early stage of adolescence, but it is also an unnervingly accurate indication of the psycho-sexual identity crises of the average 21st century male. There are a lot of fairly unattractive aspects to the 30-something "independent filmmaker" Chris Waitt that women out there will instantly recognise  – nonchalance, self-absorption, unreliability and, of course, an enduring penchant for comic books and action figures.

However, it could be said that by taking the (brave or foolhardy?) decision to turn the camera on himself and document a litany of failed relationships, Waitt has done something that could even be described as heroic. His film opens an uneasy window into the slacker soul, with honesty so endearingly brutal that he shows all of us pot-smoking idlers up to be psychological car crashes just waiting to happen.

Sure, on one level Waitt is simply the ultimate post-grunge layabout, sauntering around with a boom mic and a laissez faire attitude that would make a diazepam addict look lively, but there is a more serious side to this documentary that becomes ever clearer as his myriad problems and inadequacies come to the fore. The moments of true comedy genius (cue the ex who threatens to take him to court and refuses to talk to him unless it's from behind a curtain, her typed answers related Stephen Hawking-style) are balanced with some of genuine sadness, and some that will make most men recoil in horror. Having one's testicles beaten in a dominatrix's dungeon, in pursuit of a long absent erection, for instance, could be classed as borderline insanity.

A Complete History of My Sexual Failures is out on June 27th. Watch the trailer below.
