No sex tonight? Blame Game Of Thrones

You might think that watching Game Of Thrones with its many sex scenes would get you in the mood, but the opposite is true according to one Cambridge University statistician.

Professor David Spiegelhalter says that couples are having sex less frequently than they were 30 years ago and he blames this on the rise of "massive connectivity" – with the likes of Netflix, smartphones and box-sets bringing 24-hour entertainment into our homes.

Surveys suggest that the average UK couple had sex around five times a month back in 1990 – but now it is just three times a month.

Speaking at the Hay Festival, Prof Speigelhalter said: "The point is that this massive connectivity, the constant checking of our phones compared to just a few years ago when TV closed down at 10.30pm or whatever and there was nothing else to do.

"Now people are having less sex... I think it's the box set, Netflix. OMG I've got to watch the entire second series of Game of Thrones."

He then went on to joke that: "At this rate by 2030 couples are not going to be having any sex at all."
