Most women have been on the receiving end of the odd wolf-whistle and we often think of the guys not-so-secretly checking out a passing girl.

But a new survey has revealed that it's the girls that are checking out the boys' behinds.

The results are from The Prostate Cancer Charity, whose new initiative 'Unite ByCycling' is attempting to encourage the public onto their bikes to raise awareness of prostate cancer.

Amazingly a quarter of the ladies who took the survey admitted to taking a quick peak at a passing cyclist's bum while only a third of men confessed to the same desire for a sneaky look.

The boys, in fact, were more interested in checking out the gear the rider was wearing.

Of course, for the girls, what better opportunity to examine the male form than those skin-tight shorts? Especially when cycling makes for pert and toned behind.
