Sydney, Nov 7 (IANS): Australians have become more adventurous in their sex life, says a new study, but adding that the couples are having sex less compared to 10 years ago.

Couples are having sex around 1.4 times a week, compared with 1.8 times 10 years ago, said researchers from University of New South Wales (UNSW), La Trobe University and University of Sydney.

"It is often the man who is driving the frequency. Women are often kind of going, 'Look, I'm exhausted but do it if you like'... if there is less of that happening, that would reduce the frequency,” professor Juliet Richters from University of New South Wales was quoted as saying.

Technology has taken over our daily routine, Richters said, adding that the time spent online could be impacting our sex lives.

To find the results, researchers spoke to 20,000 men and women aged between 16 and 69 as part of the second Australian Study of Health and Reproduction.

They found that Australians are frequently engaging in more daring acts in the bedroom but the frequency has gone down owing to late night online activities.

Condom use had also become more common while use of protection during a first time continued to increase, researchers noted.

Nearly half of the people under 60 also admitted to watching pornography compared to a decade ago, Daily Mail reported.
