The title is typical of the stream of unfunny double entendres by Robin Gough dignified with being called a script ("I like a man who keeps his tool where he can get at it..."), but aside from looking painfully cheap - apart from the Holiday Inn used at the conclusion - and the horrible clothes worn by most of the men it stands up remarkably well to today's rigorously PC standards.
The interview panel vetting hero Jeremy Bulloch are all women (and at least two are obviously of mature years), most of the women are good-humouredly unflappable (and several holding down responsible jobs) while actively enjoying sex; gay characters of both sexes are matter-of-factly introduced into the narrative and one of the women he ends up romping with is black.
It's usually women who in reality complain about mens' disinclination to commit; yet here despite the fact that the two of them are already enjoying a highly satisfactory love life it's the hero who wants to get married and his gorgeous big-haired girlfriend who makes it the subject of the bet that gives the film it's title before she's prepared to tie the knot.
