Britons are least comfortable talking about their sex lives and their finances, a survey has found.
Earlier, politics and religion were the least-liked subjects, but now sex and money have replaced them, the Daily Mail reported.
Almost a third of respondents said they are uncomfortable discussing their sex lives or infidelity with even their closest friends.
Money comes third, with over a quarter saying they would refuse to talk about their finances with people close to them.
Many would not even discuss their salary.
The value of their home, politics, serious illness or religion are things that people will discuss more openly, according to the survey of 2012 respondents conducted on behalf of O2 for their All About You Report, commissioned to mark the launch of the new Samsung Galaxy SIII.
