Millennials are a technically savvy generations with a digital sixth sense. But it seems there's one area they've lost interest in.

Last week, the Public Religion Research Institute (PRRI) published a survey on the millennials' view on sexuality, religion, politics, and morality.  Among the findings, what stands out that millennials are having less sex in comparison to older generations.

A 2013 national survey by University College London found that millennials are having sex an average of 4.9 times a month for men and 4.8 times for women, compared to 6.2 and 6.3 respectively a decade ago.

One of the possible explanations, the study, revealed is that “42 percent of millennials find casual sex immoral.”

Another theory has to do with technology. “Millennials are attached to their smartphones. Whether they are out with friends or in bed with their significant other, they are tweeting, taking selfies and posting them on Instagram,” explained life coach Sujeiry Gonzalez.

Sound familiar?

Hannah Slapper argued in a Guardian article that besides technology the fear of missing out (FOMO) gives sexual anxiety.

“One of my ex-boyfriends would, as standard, roll over and check his Blackberry as his first post-coital act. After a while, I started to do the same. There was an unanswered question: what have I missed? It became a serious issue, something we subconsciously asked beforehand — what would we miss if we had sex now? Is there time for this? Would it be more convenient later?” Slapper said.
