People with wide, square faces have higher s3x drives and are more likely to cheat , a study has found.
Researchers have found those with broader facial features were more aggressive and more s3xually driven.
The team led by psychologist Steven Arnocky at Nipissing University, Ontario, measured the faces of 145 undergraduates who were in relationships and interviewed them about their s3x lives.
Those with wider faces had more relaxed attitudes about casual s3x and were linked with tendencies such as unethical behaviour, prejudice and psychopathic traits.

They were also more likely to be wealthy and more attractive to the opposite s3x for a one night stand.
The researchers hope the findings will shed light on the role that facial features play in s3xual relationships and mate selection.
Each student completed a questionnaire about their interpersonal behaviour, s3x drive, s3xual orientation, the chances they would consider cheating.
They were also asked about socios3xual orientation – seen as a measure of how comfortable you are with the concept of casual s3x – and how many times they masturbated in a typical month.
The researchers took a picture of each student to analyse their facial width-to-height ratios .
Dr Lefevre has previously found that men with wider faces tend to have higher levels of testosterone but warned against over simplifying his latest findings.

“One thing that is important to remember is that we are seeing relatively small correlations here,” she said.
“That means that there is only a tendency for wider-faced people to have a greater s3x drive, not that every person with a relatively wide face is a s3x maniac.”
Previous experiments have wider faces with traits including prejudice, psychopathy, success, ambition, questionable ethics and attractiveness.
The researchers found a similar but weaker trend in a separate group of 314 young Canadian adults.
The study appears in the journal Archives of s3xual Behaviour.
