1. Blame it on our noggins. Scientists say one of the most glaring differences between the male and female brain is that men have a sexual pursuit area that is 2.5 times larger than the one in the female brain.

As Louann Brizendine, M.D., author of The Male Brain explains it, just as cavemen sought out multiple mating partners so they could produce as many offspring as possible, the brain of the modern-day male (even a happily hitched one) is more or less programmed to always be on the lookout for a fertile mate.

Not to say that men intend to physically pursue any “visual enticement” they encounter, but there is still a deep-seated need to “check out the goods.”

2. Testosterone plays a big role, too. Duh. We guys have six times more of this libido hormone surging through our veins than women do. Columbia University researchers found that testosterone impairs the impulse-control region of the brain.

In other words, most guys likely look before they think.

3. Visual creatures that we are, there’s also the “eye candy” factor. A new study shows that while women tend to feel attracted to familiar faces, men are more turned on by someone they’ve never seen before. I believe this “novelty” theory holds true with objects, as well as women.

The next time you catch your man turning his head to get a better look at a hot chick, ask yourself this: Would you get on his case for checking out a cool new car that just drove by? I didn’t think so.
