Women with wide hips have more sexual partners & one-night stands

A new study led by Professor Colin Hendrie, has revealed that women with wide hips are more likely to have one-night stands and more sexual partners  because their birth process is generally easier and less traumatic for them than for smaller-hipped women (below 31cm).
More specifically, the women for whom one-night stands accounted for three out of every four of their sexual relationships had hips at least 0.8inches (2cm)  wider than those who had fewer one-night stands.
He said:

'Women's hip width has a direct impact on their risk of potentially fatal childbirth-related injury. It seems that when women have control over their own sexual activity this risk is reflected in their behaviour.Women’s sexual activity is therefore at least in part influenced by hip width"
