There is a new way of learing secrets about our sex lives, scientists have said.
American researchers have found that the human voice can reveal details about people's sexual past.
They also discovered that people really can tell if another person is attractive simply by listening to them.
In a study, volunteers were asked to rate, out of 10, the "attractiveness" of different voices which were played on a tape.
The researchers at the State University of New York, in Albany, found that the voices which received the highest ratings belonged to people who had more active sex lives.
In addition, the same people were more likely to be "good looking" - fitting the conventional stereotypes of having broad shoulders and narrow hips for men, and a narrow waist and broad hips for women.
In the study, 149 undergraduates were asked to record their voices as they counted to 10.
Without seeing the other speakers, they were then asked to rate them on voice-attractiveness, on a scale on one to five, five being the most attractive.
Half the students were also asked to fill in an anonymous questionnaire about their sexual history.
Those who had the highest rated voices reported having had sex at an earlier age and having had more sexual partners.
The study is published in the current issue of the journal Evolution and Human Behaviour.
