Scientists reveal the 'secret' to an amazing sex life

Nothing's sexier than a spontaneous nookie when you least expect it, right?

Actually, wrong, according to a new study. 

Apparently, the key to an amazing sexual relationship is forward planning...

Latest research found that scheduling a time and date in advance (and sticking to it) is the key to keeping the spark alive in the bedroom.

Scientists looked into the sex lives of almost 1,000 couples, most of which were heterosexual.

They asked the couples to rate how easily they could be aroused, how inhibited they were, and whether they had any issues around sex.

Those who schedule it in and make sure they're ready on time are less likely to feel unfulfilled or inhibited during the act, the study found.

Apparently, men who are conscientiousness (efficient and organised) are more likely to want to satisfy their partner sexually, which in turn leads to "better sexual function of their partners".

"High conscientiousness can be especially beneficial when it comes to putting effort into a satisfying sexual life, or to postpone one's own needs and interests to focus on resolving a sexual problem within the context of committed, long-term relationships," the researchers added.

The study also debunked a popular myth, that sex does not decline with age.

"Many of our older couples were still sexually active and quite satisfied with their sexual lives," said the researchers.
