Why do men with girlfriends look at other women?

According to Dennis Prager, men are naturally programmed to want more than one woman, despite being in a monogamous relationship

Ever wondered why men in relationships still check out other women?

Then look no further for your explanation.

Because American 'academic' Dennis Prager has cleared things up - he says men look at other women simply because they are 'other women'.

According to the President of Prager University in America, the good news is that while most males are excited by other female forms, it doesn't mean they are dissatisfied with their own partner.

And the bad news? Even men in happy relationships will still find some women more attractive than their own girlfirend.

But while your boyfriend might check out a girl in a bikini on the beach while you're on holiday together, it's not the end of the world, according to Mr Prager.

Prager added: "Men find other women attractive, in large measure, just because they are other women.

"Men are programmed by nature to want variety, indeed endless variety."

But while your man might take a sneak peek, the professor assures insecure girlfriends that if their relationship with their boyfriend is solid, then they have nothing to worry about.

He said: "More than anyone else in the world, he wants you. And if you don't believe me, ask him."

Prager University is an online resource promoting 'knowledge and clarity' via a series of 5-minute free courses. It is not an accredited academic institution.
