The 100,000 Scottish Government campaign "Sexmas Survival Guide" has angered the Church of Scotland and the Catholic Church, who also disapprove of the website's innuendo-laden approach to discussing sex.
Rev Alan Falconer of the Kirk's St Machar Cathedral in Aberdeen said: "This would not be appropriate at all. This detracts from the festival for it to be classified in this way."
John Deighan, the parliamentary officer for the Catholic Church, said: "The advice should be more respectful. Using the word Christmas like that is symptomatic of a whole philosophy that undermines their safe-sex strategy.
"They don't show enough delicacy of language and they don't show enough respect."
